original font-units (FU) to have them scaled later ( fu * pixelScale / unitsPerEM )
Scaling from font-units (funits, or FU) is now performed by the renderer itself,
i.e. applying the scale-factor 'fontPixelSize / font.getMetrics().getUnitsPerEM()'
to the PMV matrix to render the whole graph GLRegion.
This finally provides proper device and resolution independent font utilization.
Further, preliminary kerning has been added.

Also ...
TypecastFont:
- getGlyphID(..) getGlyph(..) enforce symbol mapping to Glyph.ID_SPACE Glyph.ID_CR,
as some fonts ave an erroneous cmap (FreeSerif-Regular)
- add getKerning(..)
TODO: Add binary search
- Set TypecastFont.USE_PRESCALED_ADVANCE := false,
i.e. dropping all prescaled pixel-sized advance values mapped to font pixel-size
as we utilize font-units only for later uniform scaling.
- Drop virtual getPixelSize() and add static FontScale.toPixels(..)
- Add fullString() for debugging purposed, including some font tables
