How about assigning fb_image.{bg_color,fg_color} to -1 if not color
expanding?  Since the pseudo_palette will not exceed 255, this should be
safe.

In order to do this, fb_imageblit has to support transparency (using a
transparency bitmask).  Userland apps will rarely have rectangular mouse
cursor pointers.  Also, it will need to support ROP's invert and copy. 
This will break fb_imageblit.  

Also, we have to double-buffer what's underneath the cursor.
