345d9bfe19 A zero source rect is valid for blitting 
A zero sized source rect draws pixels sourced from a 0x0 region on the source surface.

1aea43846e Don't use BlitARGBto555PixelAlpha() for SDL_PIXELFORMAT_ARGB1555 
This didn't properly take into account destination alpha.

80da805688 build: Fix testprocess invocation during "as-installed" tests 
During build-time testing, we can use `$<TARGET_FILE:childprocess>` to
pass the just-built childprocess executable to it as an argument, but
during "as-installed" testing we need to use the installed path of
the childprocess executable instead.

4c48ff51f8 render: SDL_RenderPresent now behaves when a render target is currently set. 
It'll temporarily unbind it, draw letterboxing if necessary, present, and
then rebind the previous render target.

54459def69 render: Remove the logical presentation render target. 
Now we render directly to the window, scaling as appropriate. This fixes some
concerns the render target introduced, like the quality of the final scaled
output, how to step outside of the logical size temporarily to draw some
things sharply at the native resolution, and loss of sub-pixel precision.

Fixes #8736.

6ec8b1a173 Throttle tickle reports to PS4/PS5 controllers 
UpdateDevice() can be called at an arbitrary rate, so we need to
pace ourselves to avoid filling up the rumble queue with these.

57418475ce kmsdrm: Keep fd around if we can drop master 
Modern kernels (v5.8+) allow non-root usage of drmDropMaster(), so
we can hold on to our fd after dropping master on it. This fixes
populating drm_fd in the KMSDRM SysWMinfo when using Vulkan.

Also add a missing error check for open() while we're here
