Subject: Fix queue_draw on grits_tiles
X-Git-Url: http://pileus.org/git/?p=grits;a=commitdiff_plain;h=6793e7a7f7752e8924c40c0e0c99e857350d7356

Fix queue_draw on grits_tiles

Any tile other than the top level tile wouldn't queue draw correctly
because it didn't have direct access to the viewer. Just search up until
we find it..
