Ok, I hate to admit it at this point.. but Ingo was right on the
recommendation to move the OpenGL kit into Mesa.
I'm still worried that us forking Mesa 7.8.2 may be a bad idea,
however at this point we have few other options. It's going to be
quite a bit of work to get Mesa 7.8.2 creating our libGL.so.
At the moment I have the following code i'm preparing to submit
the following targets to Mesa mainline:
libGL.so
The code from our OpenGL kit within Mesa
haiku-softpipe
The swpipe renderer from our code. This is the gallium
code i've been working on for a while that includes llvm
optimizations, I think moving it into Mesa may solve a lot
of the issues i've been having with LLVM symbols.
I don't plan on moving the gcc4 swrast renderer into Mesa
at this time. haiku-softpipe should offer a substantial
performance boost. Long term there isn't any reason the swrast
driver can't go into Mesa, but gcc2 takes priority once gcc4 is
working.
I have a recipe constructed that creates the following:
* mesa - OpenGL kit LibGL.so dispatch code
* mesa_devel - OpenGL kit headers
* mesa_swpipe - OpenGL SoftwarePipe renderer
I'm still sorting out some linking issues with mesa_swpipe, but
the libGL.so in mesa is functioning.
For those who care:

be submitted to Mesa upstream.

-- Mesa 9.3 recipe. 9.3 is the next version of mesa, this is relly just
