I figured it out, sorry for asking so fast before I even try it myself.

Basically, I convert to and from raw, and just copy the bits and pieces in
the right place.  Here's part of my code, where "image" is the final one,
and "char_image" is one of the smaller (I loop through all of them).

        Raw.sets (GlPix.to_raw image) ~pos:(3*(i*image_w + j + c*char_w))
             (Raw.gets (GlPix.to_raw char_image) ~pos:(3*(i * char_w + j))
~len:3)

Best,

Orlin
