Subject: Another "if it ain't broke, don't fix it" moment.  Revert some more
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6c5402bccdc83173f645de34830a45cbb52436a4;p=mesa.git

Another "if it ain't broke, don't fix it" moment.  Revert some more
code in _glapi_set_dispatch to its 1.74 form.  This fixes a "problem"
with buggy apps that make GL calls with no bound GL context (i.e.,
Enemy Territory during shut-down).
