Calculate draw bounds in drawEdgeAAImageSet
Calculate draw bounds in drawEdgeAAImageSet

This will allow SkiaRenderer to provide image filters on the SkPaint
instead of using an explicit saveLayer, where they must calculate the
draw bounds. Once SkiaRenderer provides filters that way, they will
automatically take advantage of any implicit layer optimizations we can
add down the road.
