From fc454c16c84d159767273a21019fbd65572f3bad Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Samuel=20R=C3=B8dal?= Date: Wed, 6 Feb 2013 09:18:19 +0100 Subject: Fixed Canvas ImageData pixel values not being settable to 0. Someone probably figured "since the data is all initialized to 0 to begin with, we can skip 0 values". However, it's possible to temporarily set a value to other than 0 and then back to 0, a fully valid use case that we need to support.
