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. Comments? -Brian
