This may not solve your bug, but realize that textures images
in OpenGL (as on Impact either directly in OpenGL code or
indirectly through IGLOO) need to be power-of-two in size in
both S and T directions. Also note that when any toolkit fixes
non power-of-two tetxure for you, it will probably scale up to
the next bigger size rather than down. This is an important
issue: IRIS GL let you slide on this and would rescale for you
upon texture load, OpenGL does not.
