Since FXIcon is derived from FXImage, you can make it the destination
of drawing operations [after create() generates its off-screen 
X11-server
resident buffer].

So, make a mini-image of your badge, then draw it onto the base icon,
then draw the icon to the screen repeatedly.

The difference between FXIcon and FXImage is, however, that the FXIcon
also has two additional 1-bit buffers for the mask and "etch" mask.

You may need to find some way to update those as well [I have no
super-easy solution for it, maybe restore() local buffer from updated
server-side buffer, and regenerating the masks, is the best idea for
now.
