The `all()` function only represents bitflags known in the core of
Vulkan; it omits all bits added by extensions making this function
unrepresentative and has hence been scheduled for removal for quite some
time to get rid of the confusion it causes.
Alternatively the generator could be taught to collect bitflags added by
extensions, but new extensions get added over time skewing available
values in ash versus the current driver/environment. This makes the
value from `all()` unreliable and fragile at best.
`-` and `-=` (`sub()` and `sub_assign()`) are also controversial by
nature since the underlying value represents an integer but the
implemented math uses bitwise operators. This is a confusing design
pattern and the caller better replaces their uses - if any at all - with
`foo &= !BAR`.
* Mark EntryCustom::new_custom as unsafe
Passing a badly-behaved `load` function can invoke undefined behavior.
* Document required feature for Entry
* Support linking Vulkan directly
This is the preferred pattern in most environments when an application
cannot function without Vulkan, as it saves the libloading dependency,
eliminates an error case, and makes the Vulkan dependency visible to
the OS.
* Rename libloading feature to "loaded"
* Link by default
* Guide users towards linking the loader directly
* Remove unnecessary error type
InstanceError::LoadError was never constructed.
* Unify entry types
Simplifies the interface and allows a bunch of code to become
monomorphic.
* generator: Add edegecases for broken Video extension enum variants
* Replace deprecated `make_version()` with `make_api_version()`
* generator: Use the same predicate for push_next and its traits
Some structs turn out to be root structs when their name is not in the
`root_structs` set, even when they themselves extend another struct.
This was already taken care of for `push_next` which is emitted in this
situation, but the trait referenced by `push_next`'s `T` bound is still
relying on the `extends` field to not exist in `vk.xml` at all, leading
to it not being generated despite `push_next` needing it.
Fixes: 215511f ("Implement ExtendXXX for multiple root create infos if
there are more than 1")
* Update Vulkan-Headers to 12.175
* generator: Generate low-level structs with bindgen (for vk_video)
According to specs for Device Memory (section 10.2), memory types are
topologically sorted by their property flags so the two-pass memory
type selection is unnecessary.

According to specs for vkGetPhysicalDeviceSurfaceFormatsKHR(), at least
one surface format must be returned, and returned formats must not be
VK_FORMAT_UNDEFINED.
* Fix literals in vk.rs
* Address all the other clippy lints in ash
* Module level clippy lint
* More lints
* Make hashmaps generic for clippy
* Remove unused macro import
Load the example shader and texture files with `include_bytes!` so
that they can be run from the root project directory. Previously,
`cargn run --bin <EXAMPLE>` could only be run from the `examples`
directory.
