From 923cadc12b993a0b41200750f151d73662856482 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Samuel=20R=C3=B8dal?= Date: Tue, 9 Jun 2009 13:23:08 +0200 Subject: Prevented pixmap FBOs from growing too big. If we're painting to very wide and then very tall pixmaps we don't want the FBO to grow to max_width * max_height, instead we should recreate the FBO if it grows too large compared to what's being painted.
