* Fix no primary monitor panic in XWayland
In this case try to use the first existing monitor instead of panicking.
Fixes#317
* Shift no monitor panic to x11::get_primary_monitor
* Update changelog with xll get_primary_monitor fallback
* Implement public API for high-DPI #105
* Recover get_inner_size_points and get_inner_size_pixels and change their implementation assuming get_inner_size() returns size in pixels
* Update changelog for high-DPI changes
* Add an i386 target to travis
* Fix X11 on 32bit architectures
One would hope 32bit X11 was dead by now but apparently not :). Fix
the window hint setting code to not assume window IDs are 64bit as
apparently they are not in 32bit arches.
* wayland: don't create a second event_queue
As each EventsLoop has its own context, this is no longer necessary.
* wayland: buffer events rather than direct dispatch
Changes the behavior of the event loop to first internally
buffer the events generated by the wayland handlers, and then
dispatch them to the client's closure.
- It simplifies the event loop logic
- It makes it possible for the user to call window methods such as
`set_title()` or `set_inner_size()` without causing a deadlock
* wayland: add is_ready() & fix protocol errors
Adds a `is_ready()` method to the windows to advertize
when it is legal to start drawing, and fix a few wayland
protocol mishandling in the process.
