  * There are many bounds in skia. A circle's bounds is just its center extended by its radius.
  * However, if we stroke a circle, then the "bounds" of that is larger, since it will now draw

  * effects/attributes that can modify the effective bounds of a given primitive -- maskfilters,
  * patheffects, stroking, etc.  This function takes a raw bounds and a paint, and returns the
  * conservative "effective" bounds based on the settings in the paint... with one exception. This
  * function does *not* look at the imagefilter, which can also modify the effective bounds. It is
