Subject: mesa: add control for categories of application-provided messages
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f6f309394036ff5228f6351435a5eff202ef0008;p=mesa.git

mesa: add control for categories of application-provided messages

This state is needed for deciding whether or not to log
application messages with IDs that haven't been specifically
passed to glDebugMessageControlARB yet.

State for each individual ID number ever passed to
glDebugMessageControlARB (per-context) still needs to be added.
