Frank Praznik 423a82cd4b wayland: Enforce or override libdecor minimum window size 
libdecor plugins can change the min/max window size values internally to enforce a minimum window size, and errors and crashes can result if the window size is below the internal limit.

On versions of libdecor >= 0.1.1, the minimum width and height can be queried and the minimum required window size will be enforced. The application requested window size is still respected, however, the actual window may be slightly larger than the drawable area to accommodate the required libdecor minimum size.

On version 0.1.0 of libdecor, which lacks the function to retrieve the minimum size, the internal limits are overridden before committing a frame, so that the internal limits always match the window size as a workaround, even if the window is technically smaller than the plugin would normally allow.

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.

Sam Lantinga 7f23d71b6a Added SDL_modf() and SDL_modff() 
This function is useful for accumulating relative mouse motion if you want to only handle whole pixel movement.
e.g.
static float dx_frac, dy_frac;
float dx, dy;

/* Accumulate new motion with previous sub-pixel motion */
dx = event.motion.xrel + dx_frac;
dy = event.motion.yrel + dy_frac;

/* Split the integral and fractional motion, dx and dy will contain whole pixel deltas */
dx_frac = SDL_modff(dx, &dx);
dy_frac = SDL_modff(dy, &dy);
if (dx != 0.0f || dy != 0.0f) {
    ...
}

Daniel Gibson ac8a041541 SDL_main for Win32: Get rid of console_*main, add wWinMain() 
I don't think there's any point in console_*main() for non-MSVC - I think
it can't be called anyway now that SDL_main is header-only.
So I renamed those functions to main() and wmain() and made them MSVC-only

For reference, MinGW (at least the version I tested) supports both main()
and WinMain(), no matter if compiled with -mconsole or -mwindows (it seems
to prefer main() over WinMain() if both are available, in both cases).
But when building with -municode, it needs wmain() or wWinMain(), so
that case is now handled with wWinMain()
