      There's a lot I don't understand about the common code still - in

      actually supposed to do! But I'm working on it.
     
     
  Just as it sounds.

  All image data is png.  However, the png data has to be converted to something 
that the display system knows how to display.

  In order to abstract this, the cache_entry image_data pointer is basically 
private - whatever the display specific code deams to store there is fine.

  The basic idea of this is to have the caching logic all in the common code (if 
it gets a face it knows about, it will do the right thing), but have the actual 
rendering code in the client area.

  For the gtk and gtk-v2 clients, that function is perhaps a bit messier than 
need be, because those clients support different display modes (pixmap, sdl, and 
in case of gtk-v2, opengl), so what exactly is stores there may be different.

  The rescale part is jsut that - rescaling of the image.  You may decide for 
your client that you don't want to allow rescaling - that's your choice.  Just 
for the gtk clients, people wanted to be able to rescale the data so they could 
play on lower resolution displays.
