Graph GLRegion/TextRegionUtil: Enhance pre-determination of buffer-size, increase default initial 16->64 (unsued)

- Region.countOutlineShape(..) now returns unpatched 3*triangle value for indices, avoiding grow
- TextRegionUtil.addStringToRegion() uses countStringRegion(..) per default
- Added GLRegion.create(.., OutlineShape) for convenience, using Region.countOutlineShape(..)
- Refined API doc
