devdraw: fix cocoa metal _flushmemscreen for invalid rectangles (#240)
It is possible to receive multiple screen resize events, and resizeimg
would be called for different sizes, before _flushmemscreen actually
gets called with rectangle sizes different from the most recent
resizeimg call. The size mismatch would trigger illegal memory
access inside _flushmemscreen.
This commit protects _flushmemscreen by returning early if the requested
rectangle is outside of the current texture rectangle.
