Hash :9325b22e Message :Fixed bug 5113 - SDL_UpdateWindowSurfaceRects BitBlt the entire surface on Win32
Ryan C. Gordon
As discussed here:
https://discourse.libsdl.org/t/question-about-implementation-of-sdl-updatewindowsurfacerects/27561
"As you can see this function [WIN_UpdateWindowFramebuffer, in src/video/windows/SDL_windowsframebuffer.c] calls BitBlt on entire screen, even though it accepts the rects. Rects variable is not even used in this function at all. Now my question is why is that the case?"
