Fixing the bounds for effects and dirty regions so that they show up in boundsInLocal needs some way to
get reasonably accurate visual bounds in much less time.

Both effects and dirtyopts look at the bounds of a whole group where the individual nodes bounds
are as reported by boundsInLocal

This fix provides code that can provide reasomably accurate glyph bounds information in much less
time than we can do with outline bounds.

We could also potentially hook up the node's visual bounds to the same code.
