Imlib image to GdkRGB

[jca <jca mail phm vcu edu>]

  I need to do a gdk_imlib_load_image and then put the image into my
GdkRGB structure so I can manipulate it.

  Before I start writing code to paste raster lines from im->rgb_data to
my own RGB, is there a standard function to do this, already written?
  No sense in re-inventing the wheel, however simple it may be...

 Thanks,
  jca
