Subject: ilo: handle conditional rendering in the context
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d69faf851fff5d41086c9940b2fcf2aa72c40e60;p=mesa.git

ilo: handle conditional rendering in the context

Conditional rendering is not limited to draw_vbo().  Move the support to
ilo_context, and replace ilo_3d_pass_render_condition() by
ilo_skip_rendering().
