Subject: gallium: add a drawid to pipe_draw_info
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=daaf0bdf46bc5084bdba1ee5d42d994f30a65841;p=mesa.git

gallium: add a drawid to pipe_draw_info

This will allow the state tracker to inform the driver where in a
broken-up multidraw we currently are. This can then be passed into the
vertex shader.
