I found out this is not entirely correct. Clearing the screen (\e[2J)
and putting the cursor top left (\e[;H) are two different things.
I integrated the changes from this patch, but changed cls() not to put
the cursor in home position.
Also I integrated some other changes:
- Fix fbc_set_active, no longer lose memory when called multiple times
- Add 7x14 font
- properly export get_pixel
- Add fb_enable/fb_disable function so that we do not have to call into
the fb_info ops directly
- Make splash screen work again, was broken by "graphics_utils: Let
fb_open allocate the screen"
Checkout the result on -next.
