oops sorry i was unclear here: i thought, in addition to applying my 
first patch, you should change the lines mentioned.

then you should get some additionaly information when turning rendering 
on (or loading Gem,...) telling you something like "ARB texturing" or 
"EXT texturing" or "rectangle texturing support = 0"
i would be interested in those 2 lines.

(before you do that, i would also be interested in what these lines say 
now, that you have reverted to CVS)

deleting the files is NOT the recommended way.
but when you force the max-GL version to be 1.5, you will also disable 
some other stuff (among them some retangle texturing stuff, which we are 
currently trying to debug)
that is why i asked you to delete the files (in the unrecommended way) 
and compile with "full" openGL support.


if you want we probably should do this via a more interactive session 
(like irc)
