Subject: [PATCH 2/2] cairo: Constrain number of cycles in rescale filter
Pass address of the first byte after end of the source buffer
to downsample_row_box_filter() so that we can check
that we don't run out of it.
Fixes issue #736

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.
