[Piglit] [PATCH 7/7] ARB_texture_view: Test texture view format changes and lifetimes

Jon Ashburn jon at lunarg.com
Mon Oct 28 19:16:04 CET 2013


Tests texture views with data format changes. 1D textures only.
Uses multiple simultaneous views with different lifetimes and
check results via glGetTexImage().

Tested on Nvidia  Quadro 600, all subtests pass.
