Subject: [PATCH] cairo: Fix tiling patterns when pattern cell is too far
Rendering of tiling pattern which has pattern matrix moving pattern cell
far away can fail on allocation of memory. This commit solves the issue by
modifying of cairo pattern matrix so that its offset is closer to the path
filled by the pattern.
