i965: Use _mesa_geometric_ functions appropriately
Change references to gl_framebuffer::Width, Height, MaxNumLayers and Visual::samples to use the _mesa_geometry_ convenience functions for those places where the geometry of the gl_framebuffer is needed (in contrast to the geometry of the intersection of the attachments of the gl_framebuffer). This patch is to pave the way to enable GL_ARB_framebuffer_no_attachments on Gen7 and higher in i965. Reviewed-by: Ian Romanick <[email protected]> Signed-off-by: Kevin Rogovin <[email protected]>
