Subject: mesa: add debug printer for primitive name
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=aa688d1579776494640475f4a5b93f3d7fae4fcd;p=mesa.git

mesa: add debug printer for primitive name

Add a simple version of _mesa_lookup_enum_by_nr() which expects a primitive
enum (GL_POINTS..GL_POLYGON).  This avoids some annoying duplicates
when looking up primitives, such as the GL_FALSE/GL_POINTS clash.
