Subject: mesa: add KHR_no_error support for glGetTexture*HandleARB()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=530ff887ebac56d9d7f0ded48282b3e1709972b1;p=mesa.git

mesa: add KHR_no_error support for glGetTexture*HandleARB()

It would be nice to have a no_error path for
_mesa_test_texobj_completeness() because this function doesn't
only test if the texture is complete.

Anyway, that seems enough for now and a bunch of checks are
skipped with this patch.
