Graph/GraphUI AA-Quality (shader): Region: Add DEFAULT_AA_QUALITY and clipping funs for aaQuality/sampleCount; TextRegionUtil: Pass quality parameter in draw-functions

Region.DEFAULT_AA_QUALITY defaults to MAX_AA_QUALITY still
- TODO: AA shader is subject to change ..

Region.draw(..) clips the quality param (save)

TextRegionUtil: Pass quality parameter in draw-functions
- Allowing to select the AA shader

GraphUI Scene and some demos add the AA-quality param
to the status line or screenshot-filename.
- See Region.getRenderModeString(..)

+++

TestTextRendererNEWT20 and TestTextRendererNEWT21
now iterate through all fonts, AA-quality shader and sample-sizes.

Most demos and some more tests take AA-quality into acount,
demos via CommandlineOptions.graphAAQuality
