Because I need to change the foreground colour too, and every location on
the 'screen' can have a different forground/background colour.
So it could look like this....

But why would you do this when you could just change the format of your
graphic to tiff and replace the white background with transparency? This is
relatively simple to do with Photoshop or Gimp, etc. With Cocoa it's just
one line to composite the section of the image containing your character,
retaining the transparency. If your view is filled with a green background
and you composite
(NSCompositeSourceOver) the character image over top this background, only
the text part will show up with the green background showing through.
