Original change's description:
> efficiently dash very large rectangles and very long lines
> 
> Speed up dashing when lines and rects are absurdly large.
> 
> Prior to this CL, only horizontal lines were detected.
> 
> The onOnceBeforeDraw changes are there to make debugging easier.
> 
> Also folded in a change to handle dashing of zero length lines.
