Subject: mt trace: cgl: track GL context on a per-thread basis
X-Git-Url: https://git.cworth.org/git?a=commitdiff_plain;h=a4c698dfae954d04b459a9b9543d0404a4c80660;hp=a150c4a0cf9e47931f0e79986f5f79b85aa5905e;p=apitrace

mt trace: cgl: track GL context on a per-thread basis

Wrap CGL context handling calls and keep our own per-thread basis track
of the context object.
