Note that this won't compile very many shaders until vkd3d-shader's GLSL
support is much more complete.

Much like we do for e.g. shader_glsl_generate_vertex_shader().

The default behaviour for gstreamer is to use the URI to create the
stream-id. Without this, gstreamer creates a random stream-id per pad
which can cause inconsistent ordering on the decodebin src pads.

This in turn can cause issues, for example, with audio stream selection.

This is a partial cherry-pick of eda34f74c6ad from Proton.

This is necessary to prevent virtual_set_force_exec from resetting the
permissions of mappings back to --- when a non-NX-compatible module is
loaded.

Hide the icon when an app has no visible windows, or when all of its
visible windows would have no taskbar entry (i.e., they are owned or
have WS_EX_TOOLWINDOW or WS_EX_NOACTIVATE, but not WS_EX_APPWINDOW).
The dock icon returns if those conditions are no longer satisfied.

This behavior is behind a Mac Driver registry key,
EagerDockIconHiding (defaulting to true), to allow toggling it on a
per-app or global basis.

Const correctness is helpful for figuring out which fields are mutable
and which ones are intended to stay constant.

The parameter types are (size_t, size_t, BOOL).

Fix Imperium: Greek Wars (1183470) launcher scrollbar largely drawn as transparent.

The application sets a hardcoded #ffffff as the color key for transparency. On Windows, the
scrollbar parts only have very few #ffffff pixels so the scrollbar is drawn as basically opaque.
If a theme that have many 0xffffff pixels is being used, then the bug reproduces as well on Windows.
I don't want to change the light theme style for this. So let's work around this by using #fefefe
instead of #ffffff. This have little difference visually.

Based on investigation done by Santino Mazza.

Microsoft Flight Simulator (2020) requires IDXGISwapChain4.
