Ryan Dwyer 7b138e5ef0 Add CSD to border modes
This replaces view.using_csd with a new border mode: B_CSD. This also
removes sway_xdg_shell{_v6}_view.deco_mode and
view->has_client_side_decorations as we can now get these from the
border.

You can use `border toggle` to cycle through the modes including CSD, or
use `border csd` to set it directly. The client must support the
xdg-decoration protocol, and the only client I know of that does is the
example in wlroots.

If the client switches from SSD to CSD without us expecting it (via the
server-decoration protocol), we stash the previous border type into
view.saved_border so we can restore it if the client returns to SSD. I
haven't found a way to test this though.

Ryan Dwyer 4e4898e90f Fix race condition crash when view unmaps + maps quickly
When a view unmaps, we start a transaction to destroy the container,
then when the transaction completes we destroy the container and unset
the view's container pointer. But if the view has remapped in the
meantime, the view's container pointer will be pointing to a different
container which should not be cleared.

This adds a check to make sure the view is still pointing to the
container being destroyed before clearing the pointer. The freeing of
the title format is also removed as it is already freed when the view
destroys in view_destroy.

Ryan Dwyer b1a0e95e8e Fix crash when disconnecting output
If the output being disconnected contains views, and the views are being
relocated to another output of a different size, a transaction must
occur to reconfigure them. This means by the time
container_discover_outputs is called, the output is already disabled and
wlr_output is NULL.

I considered making it check output->wlr_output, but output->enabled
should work just as well and is more descriptive.

Ryan Dwyer bf5933c501 Implement tab cycling using mouse wheel
Firstly, a change had to be made to the container_at functions. If you
create layout `T[view H[view view]]` and hover the second tab, the
container_at functions would return the focus_inactive child. They now
return the split container itself. To compensate for this,
dispatch_cursor_button has been adjusted to find the focus_inactive
child before focusing it.

The actual implementation of wheel scrolling is pretty straightforward.
This uses handle_cursor_axis, so I took a similar approach to
handle_cursor_button (ie. creating a dispatch_cursor_axis function).

Ryan Dwyer 09733e233f Fix crash when unmapping last child of a tabbed workspace
* Create layout T[view view]
* Move the cursor into the title bar area
* Close both views

Sway would crash because container_at_tabbed would attempt to divide by
zero when there are no children.

The children check isn't needed for the stacked function because it
doesn't divide anything by the number of children.

Fixes #2636.

Ryan Dwyer df95c61044 Fix crash in workspace_wrap_children
When workspace_wrap_children is called on a workspace which has a
fullscreen child and the fullscreen child is a direct child of the
workspace, sway would crash.

The workspace's fullscreen pointer is unset when the fullscreen
container is detached and applied again when added to a parent, but in
this case the parent hadn't yet been added to the workspace which meant
con->workspace was NULL.

The fix makes container_handle_fullscreen_reparent return if there's no
workspace, and the fullscreen pointer is reapplied in
workspace_wrap_children.

Ryan Dwyer 9215ca0f01 Align titles to baseline
This does the following:

* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.

Ryan Dwyer 635ae9557c Second attempt at restoring focus when closing a fullscreen view
To reproduce the problem this is fixing, create H[view view view],
fullscreen one of the views and close it. The entire workspace will be
given focus rather than one of the siblings.

This happens because we emit the destroy event, so the seat code tries
to find a new focus, but the view it finds is still believed to be
hidden by the fullscreen view so it's discarded and the workspace is
used instead.

This clears the workspace's fullscreen pointer prior to emitting the
destroy event so that the seat code finds an appropriate new focus.

Ryan Dwyer 908095ef9a Introduce seat_set_focus_container and seat_set_focus_workspace
These are the same as seat_set_focus, but accept a specific type rather
than using nodes. Doing this adds more typesafety and lets us avoid
using &con->node which looks a little ugly.

This fixes a crash that pretty much nobody would ever come across. If
you have a bindsym for "focus" with no arguments and run it from an
empty workspace, sway would crash because it assumes `container` is not
NULL.

Ryan Dwyer 7586f150c0 Implement type safe arguments and demote sway_container
This commit changes the meaning of sway_container so that it only refers
to layout containers and view containers. Workspaces, outputs and the
root are no longer known as containers. Instead, root, outputs,
workspaces and containers are all a type of node, and containers come in
two types: layout containers and view containers.

In addition to the above, this implements type safe variables. This
means we use specific types such as sway_output and sway_workspace
instead of generic containers or nodes. However, it's worth noting that
in a few places places (eg. seat focus and transactions) referring to
them in a generic way is unavoidable which is why we still use nodes in
some places.

If you want a TL;DR, look at node.h, as well as the struct definitions
for root, output, workspace and container. Note that sway_output now
contains a workspaces list, and workspaces now contain a tiling and
floating list, and containers now contain a pointer back to the
workspace.

There are now functions for seat_get_focused_workspace and
seat_get_focused_container. The latter will return NULL if a workspace
itself is focused. Most other seat functions like seat_get_focus and
seat_set_focus now accept and return nodes.

In the config->handler_context struct, current_container has been
replaced with three pointers: node, container and workspace. node is the
same as what current_container was, while workspace is the workspace
that the node resides on and container is the actual container, which
may be NULL if a workspace itself is focused.

The global root_container variable has been replaced with one simply
called root, which is a pointer to the sway_root instance.

The way outputs are created, enabled, disabled and destroyed has
changed. Previously we'd wrap the sway_output in a container when it is
enabled, but as we don't have containers any more it needs a different
approach. The output_create and output_destroy functions previously
created/destroyed the container, but now they create/destroy the
sway_output. There is a new function output_disable to disable an output
without destroying it.

Containers have a new view property. If this is populated then the
container is a view container, otherwise it's a layout container. Like
before, this property is immutable for the life of the container.

Containers have both a `sway_container *parent` and
`sway_workspace *workspace`. As we use specific types now, parent cannot
point to a workspace so it'll be NULL for containers which are direct
children of the workspace. The workspace property is set for all
containers, except those which are hidden in the scratchpad as they have
no workspace.

In some cases we need to refer to workspaces in a container-like way.
For example, workspaces have layout and children, but when using
specific types this makes it difficult. Likewise, it's difficult for a
container to get its parent's layout when the parent could be another
container or a workspace. To make it easier, some helper functions have
been created: container_parent_layout and container_get_siblings.

container_remove_child has been renamed to container_detach and
container_replace_child has been renamed to container_replace.

`container_handle_fullscreen_reparent(con, old_parent)` has had the
old_parent removed. We now unfullscreen the workspace when detaching the
container, so this function is simplified and only needs one argument
now.

container_notify_subtree_changed has been renamed to
container_update_representation. This is more descriptive of its
purpose. I also wanted to be able to call it with whatever container was
changed rather than the container's parent, which makes bubbling up to
the workspace easier.

There are now state structs per node thing. ie. sway_output_state,
sway_workspace_state and sway_container_state.

The focus, move and layout commands have been completely refactored to
work with the specific types. I considered making these a separate PR,
but I'd be backporting my changes only to replace them again, and it's
easier just to test everything at once.

Ryan Dwyer f5b9815128 Prepare arrange code for type safe arguments
This commit changes the arrange code in a way that will support type
safe arguments.

The arrange_output et al functions are now public, however I opted not
to use them directly yet. I've kept the generic arrange_windows there
for convenience until type safety is fully implemented. This means this
patch has much less risk of breaking things as it would otherwise.

To be type safe, arrange_children_of cannot exist in its previous form
because the thing passed to it could be either a workspace or a
container. So it's now renamed to arrange_children and accepts a list_t,
as well as the parent layout and parent's box.

There was some code which checked the grandparent's layout to see if it
was tabbed or stacked and adjusted the Y offset of the grandchild
accordingly. Accessing the grandparent layout isn't easy when using type
safe arguments, and it seemed odd to even need to do this. I determined
that this was needed because a child of a tabbed container would have a
swayc Y matching the top of the tab bar. I've changed this so a child of
a tabbed container will have a swayc Y matching the bottom of the tab
bar, which means we don't need to access the grandparent layout.  Some
tweaks to the rendering and autoconfigure code have been made to
implement this, and the container_at code appears to work without
needing any changes.

arrange_children_of (now arrange_children) would check if the parent had
gaps and would copy them to the child, effectively making the
workspace's gaps recurse into all children. We can't do this any more
without passing has_gaps, gaps_inner and gaps_outer as arguments to
arrange_children, so I've changed the add_gaps function to retrieve it
from the workspace directly.

apply_tabbed_or_stacked_layout has been split into two functions, as it
had different logic depending on the layout.

Lastly, arrange.h had an unnecessary include of transaction.h. I've
removed it, which means I've had to add it to several other files.

Ryan Dwyer 5dbbab7bdc Remove layout.c
When we have type safety we'll need to have functions for
workspace_add_tiling and so on. This means the existing container
functions will be just for containers, so they are being moved to
container.c. At this point layout.c doesn't contain much else, so I've
relocated everything and removed the file.

* container_swap and its static functions have been moved to the swap
command and made static.
* container_recursive_resize has been moved to the resize command and
made static.
* The following have been moved to container.c:
    * container_handle_fullscreen_reparent
    * container_insert_child
    * container_add_sibling
    * container_add_child
    * container_remove_child
    * container_replace_child
    * container_split
* enum movement_direction and sway_dir_to_wlr have been moved to util.c.

Side note: Several commands included layout.h which then included
root.h. With layout.h gone, root.h has to be included by those commands.

Ryan Dwyer f4bc25bcc6 Relocate container_move, container_move_to and container_get_in_direction
* container_move is only called from the move command
* container_move_to was called from both the move command and the sticky
command, but the sticky command can easily not call it
* container_get_in_direction is only called from the focus command

Moving these functions to their respective commands gives better
separation of code and removes bloat from layout.c. These functions will
need to be refactored to take advantage of type safety, so separating
them will make this easier to refactor.

The following static functions have also been moved:

* is_parellel
* invert_movement
* move_offs
* container_limit
* workspace_rejigger
* move_out_of_tabs_stacks
* get_swayc_in_output_direction

They were all used by the move functions, except for the last one which
is used by focus.

Other changes:

* index_child has been renamed to container_sibling_index, moved to
container.c and made public
* sway_output_from_wlr has been renamed to output_from_wlr_output, moved
to output.c and made public
* container_handle_fullscreen_reparent has been made public
* sway_dir_to_wlr has been made public

No changes have been made to any of the moved functions, other than
updating calls to functions that have been renamed.

Ryan Dwyer b6058703fa Refactor destroy functions and save workspaces when there's no outputs
This changes the destroy functions to the following:

* output_begin_destroy
* output_destroy
* workspace_begin_destroy
* workspace_destroy
* container_begin_destroy
* container_destroy
* view_begin_destroy
* view_destroy

The terminology was `destroy` and `free`, and it has been changed to
`begin_destroy` and `destroy` respectively.

When the last output is disconnected, its workspaces will now be stashed
in the root. Upon connection of a new output they will be restored.

There is a new function `workspace_consider_destroy` which decides
whether the given workspace should be destroyed or not (ie. empty and
not visible).

Calling container_begin_destroy will no longer automatically reap the
parents. In some places we want to reap the parents and in some we
don't, so this is left to the caller.

container_reap_empty_recursive and container_reap_empty have been
combined into one function and it will recurse up the tree.

Ryan Dwyer 0f6d212629 Send output enter/leave events correctly
Previously we used a reparent event to detect when a view changes
parent, then sent an output enter/leave to the surfaces if needed. This
worked for tiling views but not floating views, as floating views can
intersect another output without changing parent.

The solution implemented for floating views also applies cleanly to
tiling views, so the previous method has been completely replaced and
the reparent event has been removed.

This introduces a new function container_discover_outputs. This function
compares the container's `current` position to the outputs, sends enter
and leave events as needed, and keeps track of which outputs it's
intersecting in a new `container->outputs` list. If it has entered a new
output with a different scale then the title and marks textures will
also be recreated at the new scale.

The function is called when a transaction applies. This is convenient as
it means we don't have to call it from various places.

There is imperfect rendering when a floating view overlaps two outputs
with different scales. It renders correctly for the most recently
entered output, but there is only one title texture so it renders
incorrectly on the old output.

Ryan Dwyer 2b5a404ac9 Replace hacky L_FLOATING container with a list
Workspaces previously had a magical `workspace->floating` container,
which had a layout of L_FLOATING and whose children were actual floating
views. This allowed some conveniences, but was a hacky solution because
the container has to be exempt from focus, coordinate transactions with
the workspace, and omit emitting IPC events (which we didn't do).

This commit changes it to be a list directly in the sway_workspace. The
L_FLOATING layout is no longer used so this has been removed as well.

* Fixes incorrect check in the swap command (it checked if the
containers had the L_FLOATING layout, but this layout applied to the
magical container).
* Introduces workspace_add_floating

Ryan Dwyer d6cd79c342 Implement iterators per container type
This introduces the following `for_each` functions:

* root_for_each_workspace
* root_for_each_container
* output_for_each_workspace
* output_for_each_container
* workspace_for_each_container

And introduces the following `find` functions:

* root_find_output
* root_find_workspace
* root_find_container
* output_find_workspace
* output_find_container
* workspace_find_container
* container_find_child

And removes the following functions:

* container_descendants
* container_for_each_descendant
* container_find

This change is preparing the way for demoting sway_container. Eventually
these functions will accept and return sway_outputs, sway_workspaces and
sway_containers (meaning a C_CONTAINER or C_VIEW).

This change also makes it easy to handle abnormalities like the
workspace floating list, root's scratchpad list and (once implemented)
root's saved workspaces list for when there's no connected outputs.

Commit 4b8e3a885b makes it so only one

removes the now-unnecessary code which was used to support concurrent
committed transactions.

* Instead of containers storing a list of instructions which they've
been sent, it now stores a single instruction.
* Containers now have an ntxnrefs property. Previously we knew how many
references there were by the length of the instruction list.
* Instructions no longer need a ready property. It was used to avoid
marking an instruction ready twice when they were in a list, but this is
now avoided because there is only one instruction and we nullify the
container->instruction pointer when it's ready.
* When a transaction applies, we no longer need to consider releasing
and resaving the surface, as we know there are no other committed
transactions.
* transaction_notify_view_ready has been renamed to
view_notify_view_ready_by_serial to make it consistent with
transaction_notify_view_ready_by_size.
* Out-of-memory checks have been added when creating transactions and
instructions.
