Subject: mesa: Add extension scaffolding for ARB_draw_indirect
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=56e98fe2fe0cccd86d63f4465466a9e57659f8e0;p=mesa.git

mesa: Add extension scaffolding for ARB_draw_indirect

We will reuse the same extension flag for ARB_multi_draw_indirect since
it can always be supported by looping.

Based on part of Patch 2 of Christoph Bumiller's ARB_draw_indirect series.
