Some applications use FindWindowA() with class Shell_TrayWnd to find the taskbar window on Windows.
Then GetWindowRect() is called to get the taskbar window rectangle. Finally, the taskbar window
rectangle is subtracted from the primary screen rectangle to calculate the work area. Without a
valid taskbar window position, these applications end up getting an incorrect work area and going
down the wrong path. So use the same position and size as the host system panel for explorer taskbar
when it's hidden.

Overwatch 2 verifies that every kernel callback that is run, lives in user32. Introduce a callback in user32 that just forwards to the other modules' callbacks.

Currently it's not obvious when the HLSL compiler fails, either due to a missing
feature or incorrectly coded error check, which can unnecessarily complicate
debugging.
It's legal for well-behaved programs to try to compile invalid shaders, but that
should be a rare enough case that it's worth printing it to Wine debug output
regardless.

mrac tries to get function pointers for these functions using MmGetSystemRoutineAddress, I haven't seen them being used by it, but might as well implement it since they are very easy to implement.
