System Information
Win7 x64, R9 280X, Catalyst 16.3

Blender Version
Broken: fad0c33

Short description of error
Texture when set on "extend" instead of repeat will render correctly on CPU, but will repeat on GPU for both rendered(openCL) and material(OpenGL) mode.

Exact steps for others to reproduce the error
Open attached file: bug extend v2.blend
Hit Ctrl+Z with CPU mode, it renders a uniform color (correct), switch to GPU, it renders a pattern (like if it was on repeat mode)

@Sergey, @ThomasDinges, yet another one for you to check :)

Fixed the OpenCL part, will leave the OpenGL part for another day or someone else.

Thanks for the fix. Switching between clip, extend and repeat in rendering view mode gives artifacts. Activating another view mode (like wireframe) and reactivating the rendered view mode corrects the problem.
For some reason, the original material, which made us discover the bug still doesn't work properly on GPU (CPU is ok). I'll report later when I find why.

I just fixed an issue in this fix in 2c9add965b, I don't know if it's related to the specific problem you saw but might be worth retesting with that revision.

Thanks for the fix Brecht, but seems there is indeed an issue with Clip Extension type (even after your fix) Not sure whats wrong yet.

@brecht Thank you for the fix. It solved the viewport update problem and unexpectedly also the complex material problem.
@ThomasDinges Can you provide a material where it still fails after 2c9add965b?

I've fixed an extend mode in b99f7a9.

OpenGL changes would be much more involved since proper implementation using OpenGL would require binding image per image extension type, which isn't really simple with our current GPU bindings. This is actually known limitation for now.
