Hi. I'm trying to draw a mouse pointer in GRUB. My problem is that the mouse is a little bit special. I would like to draw that bitmap last and ask damaged bitmaps to do refresh when refreshing the mouse pointer. But GRUB does not work that way (Or have I misunderstood? I'd prefer not to refresh all bitmaps!) So what I would temporarily want is a way to copy framebuffer data for the mouse-driver to store when undoing the damage. This probably won't work in all situations, but it's still better than nothing. GRUB has no functions to extract framebuffer data into a bitmap for the higer levels to use later. So far I have a fully working mouse but it leaves "snail trails" on other bitmaps. :) Does anyone have any hints?
