Update window, display, and game capture to always bilinear filter in
linear space, even if the source texture is not SRGB typed. This helps
resolve confusion in situations where we were filtering in nonlinear
space vs. linear space, like when toggling an empty crop filter.
A user has reported that toggling the cursor can cause exceptions.
Propagate that information upward, so we can reset the capture.
Display capture never needed to call the function in the first place.
Shuffle around window capture code to make a common reset function.
Builds on PR #4663.
Add display capture support via winrt_capture_init_monitor. Almost all
of the existing window capture code is reused.
Rename winrt_capture_init to winrt_capture_init_window for symmetry.
Starting with Windows 10 2004, we can disable WGC cursor capture, and
provide a user toggle. We swap out WGC support for our own though
because ours does not break hardware cursor support.
