- Remember to flip the foreground and background color attributes in

Browse Source 
gfb_draw if 'flip' is specified.  This causes the mouse cut region
  to be displayed in reverse color so it is visbile.
- Use the "other" implementation of gfb_cursor for the creator driver,
  which doesn't assume there is a hardware cursor.  It seems that the
  hardware cursor that creator provides doesn't display the character
  under the cursor in reverse colors, so the driver does this manually
  and uses the hardware cursor for the mouse pointer (which it also works
  much better for).  This is wedged here because it required less hoops
  than accessing the syscons vtb from inside the video driver, which is
  needed to read the character and color attributes under the new cursor
  position.
