This MR optimizes and makes correctness improvements to the window_surface flush implementation:
1. Implement a buffer queue to avoid constantly allocating new buffers.
2. Take into account the bounds of the window_surface flush and track per-buffer damage to reduce copying from the window_surface.
3. Copy from the window_surface only pixel data that lies within the flushed bounds. Maintain the latest contents for pixels outside these bounds, by copying them from the latest valid buffer.
4. Communicate damaged surface regions to the compositor to allow it to perform more efficient pixel data transfers (e.g., texture uploads).
Thanks!

In a declaration with multiple variables, the variables must be created
before the initializer of the next variable is parsed. This is required
for initializers such as:
```
float a = 1, b = a, c = b + 1;
```
The solution is to parse the type information in the same rule as the first variable ('a' in this case) so that it can be declared before the parser reaches the initializer for the following variables.
To initialize the following variables, the type information is passed along from the first variable's struct parse_variable_def to the next and so on.

On my Nvidia GeForce GTX 1050 Ti `ddxddy.shader_test` doesn't pass because of considerably different numeric results.
As Giovanni pointed out, this is because my GPU uses the fine derivate and not the coarse derivate to implement ddx() and ddy().
For this reason, the result for ddx|ddy() is quantized so that the test passes if the GPU uses either coarse or fine derivates.
Additionally, tests for both ddx_coarse|ddy_coarse() and ddx_fine|ddy_fine() are added, that expect a more precise result.

This is obviously questionable, as it requires reaching into Wine internals in
tests (beyond simply detecting whether Wine is in use).
However, we are at a point where, for d3d10 and above, the Vulkan renderer works
well enough in general to see real use [in fact, in my experience it usually
works better than the GL renderer], and at this point I think avoiding
regressions is quite important. It is currently difficult to run tests with it
when the results contain so much noise, and I think we need to solve this
problem, by actually marking which tests work on each backend.
We could in theory expose the renderer through some adapter string, but I
believe in the past applications have been sensitive about the contents of
adapter strings.
Fixing either renderer to reach and maintain parity is not feasible. The GL
renderer is not going away, but regrettably GL as an API is abandoned by
Khronos, and important features we need in order to implement some Direct3D
features will probably never be introduced into GL. Moreover, the amount of
effort that would be required to reach parity is not small, and itself would all
need to be verified manually.

> The part that doesn't thrill me is the fact that DXGI still directly accesses the VkQueue object, which I tend to see as an internal implementation detail to vkd3d. On the other hand it's nice that we don't need new API from vkd3d (even if, in the future, we were to need something other than vkQueueSubmit() and vkQueuePresentKHR()).
For what it's worth, it was a fairly explicit design decision early on to expose the underlying Vulkan objects for d3d12 devices and command queues, as well as to allow the creation of d3d12 resources on top of existing Vulkan images, for the purpose of interoperation with other Vulkan code. I.e., the idea is that it should be possible to integrate vkd3d into a larger Vulkan application to draw some parts using the d3d12 API, while everything else is drawn using Vulkan.
The internal queueing of command queue operations on the vkd3d level is unfortunate in that regard; ideally we just wouldn't do that. This MR could probably do a better job of explaining why we need to do that in some cases, and what kind of command queue operation sequences could result in out-of-order presentation.
If we're going to need to introduce a DXGI worker thread anyway, could we just make vkd3d_acquire_vk_queue() block until there are no longer any operations queued?

Sub / Function can be on one line, but only if there's brackets.
```
| Storage_opt tFUNCTION Identifier ArgumentsDecl BodyStatements tEND tFUNCTION
```
This leads to sometimes to `link_statements` being called with `head` being NULL, probably because now the `:` can be parsed as `Statement` in `BodyStatements`.
Also note that this introduces another shift/reduce conflict, could be related, but I don't understand it well enough. Feedback would be appreciated, I'm still learning bison.

Shader Model 6 introduces a 16-bit float (half) type, and 16-bit and 64-bit integer types. Storing extra info in the type enum simplifies checking if a type is any integer, floating point or numeric type, and the declaration of SPIR-V types. The benefits depend on using enum vkd3d_data_type in the backend instead of vkd3d_shader_component_type.
Patch 2 is difficult to split because types typically flow through to vkd3d_spirv_get_type_id(), so partial changes would require new calls to conversion functions which would be deleted again later.
