[Piglit] [PATCH 3/7] ARB_texture_view:Test valid and invalid targets for TextureView

Jon Ashburn jon at lunarg.com
Thu Oct 24 23:48:58 CEST 2013


The new target supplied with textureView must be compatible with the
original textures target. This tests  valid and invalid combinations.

Tested on Nvidia Quadro 600, all tests pass.
