Incorrectly rendered app

    anv/pipeline: Pull 3DSTATE_SBE into a shared helper


the Sascha Willems computeparticles demo was rendering particles (albeit incorrectly). Now however, no particles are rendered and only the gray background is visible.

The rendering issue is not fixed by the above the commit, nor by the latest branch head.

Tested under Ivy bridge driver.
