1) How do I create an image with an alpha channel (and set the value
   of the alpha channel)?  This is specifically so I can test alpha
   channel handling in Gimp-print.  Specifically, I want to move the
   alpha channel handling (and the color map handling, but that's a
   lot easier) out of libgimpprint and into the plugin.

2) It appears that thumbnail images (via
   gimp_image_get_thumbnail_data) always contain an alpha channel
   (unfortunately, this isn't really what I want for (1)).  Is there a
   reason this is the case, or am I missing something?
