Graph: Region.countOutlineShape(..) -> static, allow usage w/o instance; TextRegionUtil.addStringToRegion() grow region buffer w/ counting (as well); GLRegion.create(..) count + reuse create(.., size) static-ctor

All supported string -> region method utilize pre-calc of size and growth!

Before, GraphUI's Label0 used TextRegionUtil.addStringToRegion() and hence missed this optimization path.
