Author: Chris Wilson <ch...@chris-wilson.co.uk> Date: Tue Apr 12 19:13:22 2011 +0100 Revert "i965: Reinstate max-index paranoia" This reverts commit b4cbd2b312d53a50603e2cda925711bc9def4517. It looked like a safe sanity check. It missed the issue of the start of the buffer not being at 0, but even that was not enough to explain why setting the max vertex index caused glyphs to be dropped from the game 'Achron'. Instead, the issue appears to be related to the use of the vertex bias and so we would need to re-emit the max-index every time we adjusted the bias, so re-emitting the relocations and defeating the original optimisation.
