Fix getBBox for perpendicular paths

This patch contains two fixes for failures exposed in my previous patch:
1) We need to special-case the first bounding box in SVGRendererSupport::computeContainerBoundingBoxes. What's happening is we start with a bounding box of 0,0,0,0 and we add the union of all our child bounding boxes. The problem is that the resulting bounding box will always start at x=0, y=0, due to the initial bounding box of 0,0,0,0, so we need to special-case the first child and set the initial bounding box to our first child's bounding box.

2) My previous patch had a mistake where I failed to transform a child's bounding box using transform.mapRect().
