Eric Wasylishen 67c91353e0 Handle DPI scaling in SDL_GetWindowSurface 
Fixes DPI awareness of testdrawchessboard (previously, the surface was
being created in points instead of pixels, resulting in the demo app
only drawing in a corner of the screen on High-DPI displays)

*_CreateWindowFramebuffer()/*_UpdateWindowFramebuffer(): are updated
to use SDL_GetWindowSizeInPixels instead of SDL_GetWindowSize() or
window->w/window->h.

Most of the _CreateWindowFramebuffer backends are untested except
for Windows.

Fixes #7047
