Does it make more sense to move this arg to right before dest_id and name it
dest_target?  Otherwise it is confusing (it could be interpreted as target for
source or target for both source/dest).

Done. I also intended to do like this before, but I finally interpreted target
same as glCopyTexImage2D. glCopyTextureCHROMIUM has more arguments than
glCopyTexImage2D. It makes sense to move target to right before dest_id.
