[GEM-dev] texture mode with shader : WAs Re: pbs with GEM on macpro quad

[cyrille henry]

hello,

i don't know what changed, but i am now able to use RECT texturing with 
shader under linux.
i don't have time yet to test if my patch will get a performance boost 
like this, but i hope i'll be able to use multiple texturing now.

that will make my life easier.
