Subject: [PATCH] Fix crash when minimizing game window (#933)

Returns early if the window or framebuffer width or height = 0 to avoid dividing by zero. Checked the vector components individually instead of using `Vector2i.Equals()` because you can end up in a situation where width is non-zero and height is zero if you manually resize the window instead of using the minimize button.
