From: Alejandro Piñeiro <apinhe...@igalia.com>
This test extend the already existing getactiveattrib by testing the
new functions added by the ARB_vertex_attrib_64 specification.
One alternative option would be to directly extend that test. Having
said so, this kind of isolated subtests for the new functionality
defined on a specification is really common.
