rules for OutlineShape and add get/setWinding in Outline
Loop.initFromPolyline()'s Winding determination used a 3-point triangle-area method,
which is insufficent for complex shapes like serif 'g' or 'æ'.
Solved by using the whole area over the Outline shape.
Note: Loop.initFromPolyline()'s Winding determination is used to convert
the inner shape or holes to CW only.
Therefor the outter bondary shapes must be CCW.
This details has been documented within OutlineShape, anchor 'windingrules'.
Since the conversion of 'CCW -> CW' for inner shapes or holes is covered,
a safe user path would be to completely create CCW shapes.
However, this has not been hardcoded and is left to the user.
Impact: Fixes rendering serif 'g' or 'æ'.
The enhanced unit test TestTextRendererNEWT01 produces snapshots for all fonts within FontSet01.
While it shows proper rendering of the single Glyphs it exposes another Region/Curve Renderer bug,
i.e. sort-of a Region overflow crossing over from the box-end to the start.

win<->obj coord transformation, enhance documentation a little,
Have win<->obj coord transformation in UIShape public:
- Move SceneUIController.transformShape() -> UIShape.setTransform()
- Move SceneUIController.windowToShapeCoordsImpl() -> UIShape.winToObjCoord()
- Add UIShape.objToWinCoord()
- Add UIShape.getSurfaceSize()

endOfContour), remove redundant branch B3, add Type-2 and add code dump for testing
Realigned renderer code w/ Typecast's AWT demo:
- TTF Quadratic Shape
- The inner loop 'offset < count' is sufficient, otherwise could drop last point
- point_0.endOfCountour is valid as a last point
- Branch-3 and hence point-3 is not required as handled via B4 and subsequent B6
- Type-2 Cubic Shape
- Added .. not tested yet
Also added optional debug code dump via
java cmdline `-Djogl.debug.graph.font.Renderer.Code`,
which dumps plain OutlineShape construction code for testing
and debugging our CurveRenderer.

processString(..) to Font, cleaning up ..
Further having Font.processString() return the AABBox of the whole string's 'laidout' OutlineShapes,
which is used for (debug) Font.getPointsBounds2(..) just to validate the coordinated with
the Glyph based AABBox of Font.getPointsBounds(..).
Static TextRegionUtil.drawString(..) no more require to pass the temp AffineTransform instances (ugly).

- All pixelSize metrics methods are dropped in Font*
- TypecastGlyph.Advance dropped, i.e. dropping prescales glyph advance based on pixelSize
- TextRegionUtil produces OutlineShape in font em-size [0..1] added to GLRegion
- Adjusted demos

Use TestTextRendererNEWT01 to produce validation snaps
- Move kerning handling from Font to Font.Glyph using binary-search for right-glyph-id on kerning subset from this instance (left)
- TextRegionUtil: Kerning must be added before translation as it applies before the current right-glyph.
- TestTextRendererNEWT01 produces validation snapshots against LibreOffice print-preview snapshots
- GPUTextRendererListenerBase01 added another text for kerning validation, show more font-size details (pt, px, mm)

- Using Typecast's new git repo https://github.com/dcsch/typecast
- Preserved our changes
- Preserved loading fonts and glyph on input stream w/o font data array copies
TODO
- Maintain an original branch in Typecast w/ our changes
to ease updates. Then we merely need to change the package name.
- This also shall help to allow Typecast to use our patches,
if so desired.

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

monitor values w/ QT_SCREEN_SCALE_FACTORS syntax, use for X11
Per-monitor values are parsed if value is not a float and stored
in a given Map<String,float[2]>, parallel to a detected global_pixel_scale_xy.
The per-monitor value syntax matches QT_SCREEN_SCALE_FACTORS,
i.e. the regular expression '(<string>=<float>;)+',
e.g. QT_SCREEN_SCALE_FACTORS='DP-1=1.25;DP-2=1.25;HDMI-1=1.25;'
The per-monitor value is preferred and on X11 stored within the MonitorDevice,
matching the MonitorDevice's name.
The following env-var names are searched on X11:
"QT_SCREEN_SCALE_FACTORS", "QT_SCALE_FACTOR", "GDK_SCALE", "SOFT_SCALE"

.. otherwise, we might end up receiving a client position of 0/0, while being positioned in a different absolute place within root.
