From 1ec715ce8b126da3cfe3b383054f9a176960c218 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Fri, 13 Feb 2015 22:03:47 -0500 Subject: [PATCH] glsl: teach std140_base_alignment about samplers These functions are about to be used more aggressively for determining uniform layout. Samplers may be inside of structs, and it's easier to reuse the existing base alignment logic.
