Bug with GraphicsLib

Hi there,

thanks for the report. I believe you're trying to use 'withRGB'
using code like the following:

  module Foo where
  import SOEGraphics
  bl = RGB 0 0 0

As you've guessed, due to the way the RGB type is exported
from SOEGraphics you cannot actually see its constructor. You
can fix this by having the export list of SOEGraphics say
"RGB(..)"  instead of just "RGB".
