From 7807763dd84ae381e208f74a0f4b7476b70ffbe8 Mon Sep 17 00:00:00 2001 From: Zack Rusin Date: Thu, 13 Jun 2013 13:34:57 -0400 Subject: [PATCH] draw: fix a regression in computing max elt gl can use elts without setting indices, in which case our eltMax was set to 0 and always invoking the overflow condition. So by default set eltMax to maximum, it will be curbed by draw_set_indexes (if it ever comes) and if not then it will let gl's glVertexPointer/glDrawArrays work correctly. Fixes piglit's triangle-rasterization-overdraw test.
