From 75837dfefaef467dbf8813fbf12d8f4348a9b333 Mon Sep 17 00:00:00 2001 From: Andrzej Hunt Date: Fri, 11 Jul 2014 09:12:27 +0200 Subject: Add LOK tiled rendering divided-tile unit test. I.e. we render the same area as one larger tile, and then as 4 sub-tiles (which, when put together, should be identical to the larger tile). However currently only the top-left sub-tile actually matches the larger tile, so we have to disable the test for the remaining sub-tiles.
