 // Building aaclip meant aa-scan-convert a path into a huge clip.
 // the old algorithm sized the supersampler to the size of the clip, which overflowed
 // its internal 16bit coordinates. The fix was to intersect the clip+path_bounds before
 // sizing the supersampler.
 //
 // Before the fix, the following code would assert in debug builds.
