From 20c77ae6390451a74e2463f02c49bd7fec3dd29c Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 25 Oct 2017 02:39:20 +0200 Subject: gallium/util: remove some block alignment assertions These assertions were revisited a couple of times in the past, and they still weren't quite right. The problem I was seeing (with some other state tracker) was a copy between two 512x512 s3tc textures, but from mip level 0 to mip level 8. Therefore, the destination has only size 2x2 (not a full block), so the box width/height was only 2, causing the assertion to trigger for src alignment. As far as I can tell, such a copy is completely legal, and because a correct assertion would get ridiculously complicated just get rid of it for good.
