From 897f97566898b6ddde710c8c4e83ecf163c2c62f Mon Sep 17 00:00:00 2001 From: Ian Romanick Date: Sat, 14 Dec 2013 00:55:50 -0800 Subject: [PATCH] meta: Expand the vertex structure for the DrawPixels paths Another step leading to some code sharing. Note that the new DrawPixels vertex structure is the same as the new vertex structure in BlitFramebuffer and the others.
