Tim Ledbetter e294c96aef PixelPaint: Make merge up and down actions work with disjoint layers 
The "Merge Active Layer Up" and "Merge Active Layer Down" actions now
work with layers of different sizes. These actions now expand the
bounding rect of the newly merged layer to contain all layers being
merged. Layers which are not visible are now ignored by these actions.
