Cameron Gutman c9b03f80f8 Partially revert "Use GL_NEAREST when possible without degrading quality"
The changes to GL_NEAREST for overlay textures and disabling alpha blending in SDL renderer are left intact.

This reverts commit 0f49dca4c0.

Cameron Gutman 6e231778a2 Fix blocking during rendering rather than in waitToRender() on MoltenVK
MoltenVK does a lazy fetch of the drawable only when it's being modified, so waitToRender() is completely ineffective as is. Rendering a small empty overlay in waitToRender() forces the next drawable wait to happen in waitToRender(), before we pick the current frame to render. This removes one display refresh period of latency when using V-sync.

Cameron Gutman d997a0d0c8 Dynamically adjust libplacebo swapchain depth on macOS
Direct-to-display mode on some Macs (M4 Mac Mini) can retain our drawables, which cuts the frame rate in half if we're in double-buffered mode.

We don't want to use triple-buffered mode all the time because it increases latency when used if not required, so detect delayed presentation and enable it on the fly if needed.

Cameron Gutman 9cbba106ad Use the Metal renderer by default on all Macs
Whatever dGPU/eGPU rendering issues existed at the time I wrote that check seem to no longer happen on my RX 480 eGPU test setup running Ventura (our oldest supported OS).

It seems safe enough to enable now, especially since 7d6ce0b4c should catch broken systems and transparently fall back to AVSampleBufferDisplayLayer.

Fixes #1885

Cameron Gutman 7d6ce0b4cc Implement testRenderFrame() for the VTMetal renderer
This can be used to (hopefully) detect cases where importing the decoded frames onto the target GPU fails.

See #1885

Cameron Gutman 5faa5fece8 Don't manually override v4l2m2m buffer counts
This causes POLLERR when decoding from meson-vdec on the Libre
Computer Alta (and likely other Amlogic boards). Our requried buffer
counts were already lower than the default 16/20 configuration that
FFmpeg uses, so overriding them was just a memory usage optimization.

Cameron Gutman 51f86caac3 Fix assert on exit using KMSDRM on AMDGPU
AMDGPU disallows commits that would leave a CRTC active without
the primary plane enabled. Instead of disabling the primary plane,
simply restore the original state of the plane to avoid this.

Cameron Gutman 8326223220 Revert "Use EOS to force decoder test frame output"
It causes hangs on defective v4l2m2m decoders, and it's not always
well-supported by out-of-tree decoders either.

This reverts commit 66a30c66f3.

Cameron Gutman 6f4ced5ed6 Assume GPUs on non-x86 platforms are slow by default
This can be overriden with GL_IS_SLOW=0 at runtime
for systems with a fast GPU, though it doesn't make
much difference either way for non-KMSDRM cases.

For slower GPUs, this enables important scaling and
rendering optimizations that can substantially
improve performance (especially on fillrate-limited
GPUs common in SBCs).

Cameron Gutman 5020fc6f48 Do not reset the renderer on SDL_RENDER_TARGETS_RESET
We only need to do this on a SDL_RENDER_DEVICE_RESET where we lose the whole device.

This also reverts a56efe5 since this change is not needed when handling the reset events properly.

Cameron Gutman 2dda65078f Remove D3D9Ex focus loss hint workaround
SDL3 doesn't suffer this bug and keeping the default SDL3 auto behavior (minimize iff in exclusive mode) is a better UX.
