Reverted the order of the SDL_WarpMouseInWindow and SDL_GetMouseState
to its original sequence.
This avoids cursor warping to the center of screen on older SDL versions
It causes an additional SDL_MOUSEMOTION event when ungrabbing, but does
not cause any issues.
Move grab handling out of `nk_sdl_handle_event` to `nk_sdl_handle_grab`,
which is now called outside of the event loop.
This change makes the logic similar to the GLFW demos and fixes issues
with missed grab state changes and mouse cursor disappearing.
Addresses an issue where the Metal render driver (macOS) could not handle the clipping rectangle {-8192, -8192, 16384, 16384} and would simply draw nothing to the screen. The solution is to ensure the cliprect coordinates are not negative, which also doesn't break the other render drivers.
