From 10d104207acdf78e76e329041852c2eae9765cec Mon Sep 17 00:00:00 2001 From: Samuel Pitoiset Date: Wed, 14 Jun 2017 11:27:44 +0200 Subject: mesa: add KHR_no_error support for gl*UniformHandleui64*ARB Similar to _mesa_uniform() except that we have to call validate_uniform_parameters() instead of validate_uniform().
