      What should I do here?

      a) fix the documentation (map_scroll implicitly clears out of map bounds

  That seems fine.

      Another question: I did fix all clients (x11, gtk, gtk2) and (where

  I started seeing the same thing after I updated by system and lost the 
hardware opengl support.

  I would have thought that the software (emulated) gl support should work, but 
apparantly doesn't.  I'd need to check the output of glxinfo in both cases and 
see what is different - most likely, the software opengl support isn't 
supporting some type of visual  or the like - that is what BadMatch typically means.

  Open a bug on this so its not forgotten.  That said, if you don't have 
hardware opengl support, you don't get much by using that mode.
