David Capello 5a6bd465f5 Cache mouse cursors to avoid re-generating them on each setCursor()
This should improve the mouse movement, where a new mouse cursor was
created on each mouse movement with black & white pixels. It's a
regression introduced in ef4f691459
(which was originally introduced to improve the mouse movement
perception in a 100Hz monitor).

This might be a possible fix for:
