Subject: mesa: add varray support for UNSIGNED_INT_10F_11F_11F_REV type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1f092a95941b990f3a06fa71a3b53e15a8a112e8;p=mesa.git

mesa: add varray support for UNSIGNED_INT_10F_11F_11F_REV type

V2: fix interaction with VertexAttribFormat, since that landed after
this was originally written
