SoC idea: fix wine 2398 bug.

[Marcin Kardas]

Hi,
I'm participate in Google summer of code and I'm going to send
application with my own idea. I would like to fix popular wine bug -
http://bugs.winehq.org/show_bug.cgi?id=2398. On
http://wiki.winehq.org/OpenGL there are some ideas how to do this and
I think that this one with glViewport and glScissor is the best one.
I've made some test and it should work, but may be it will cause
another problems to solve, for example conecting X graphic context
with GLContext. Maybe I will have to rewritte wine graphics function
to use only OpenGL (or may be I will found another way). What do you
think about it?

Cheers,
Marcin.
