How many HW drivers have a conditional render switch? I think all of them,
but I'm not sure.

At any rate, should be fine for r300.

Here's my first stab at adding conditional rendering to gallium (and
softpipe and the Mesa state tracker).

It's pretty simple.  There's one new pipe_context function:
render_condition().  It specifies the pipe_query object to check
before rendering.  If the query parameter is NULL it means render
normally.

This is for implementing GL_NV_conditional_render and the
corresponding feature in OpenGL 3.0.
