Subject: gallium: added new EMIT_HEADER token
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b9518a4e39f739a31dd3f62d67563944f8c266a9;p=mesa.git

gallium: added new EMIT_HEADER token

Used to emit the struct vertex_header info for softpipe.
Before we were using the EMIT_ALL token but that's insufficient for the
draw pass-through mode.  EMIT_ALL might get removed soon...
