      draw wip

with i915g (but not softpipe).  This includes glxgears.

From a quick look, the commit is not supposed to affect the pipe drivers.  What's more weird is that i915g is affected but softpipe is not.

The commit does not compile.  I needs to use the next next commit, a192b5eeafae80f9f9e7e7e442abc5b44d583d1a.

Good catch. Yea, the sse runner is not great. We might need to force GALLIUM_NOSSE=1 as default soon. Please commit.
