* SDL_SetWindowDisplayMode() => SDL_SetWindowFullscreenMode(), returns bool
The following functions have been removed:
* SDL_GetClosestFullscreenDisplayMode()
* SDL_GetDisplayDPI() - not reliable across platforms, approximately replaced by multiplying SDL_GetWindowDisplayScale() times 160 on iPhone and Android, and 96 on other platforms.
* SDL_GetDisplayMode()
* SDL_GetNumDisplayModes() - replaced with SDL_GetFullscreenDisplayModes()
