Use w/ UISceneDemo03 Type Animation...
A list of GlyphShape can be created via GlyphShape.processString(..),
which preserves all details incl. intended original unscaled position and its kerning.
Whitespace or contourless Glyphs are dropped.
A GlyphShape is represented in font em-size [0..1] unscaled.

- Using GlyphShape and apply scaling via its Shape.setScale()
- Recalc fontScale per used text
- Refined 'arrival' criteria and smoothing out near target w/ speed-up rotation
- Using GraphUIDemoArgs to parse common commandline demo options

- Contrary to UISceneDemo0[01], here we
- Call the Scene GLEventListener methods manually
- Issue glClear* ourselves
- Using own PMVMatrixSetup
- gluPerspective like Scene's default
- no normal scale to 1, keep distance to near plane for rotation effects. We scale Shapes
- translate origin to bottom-left
- Scale Button not by screen-size but Scene.getBounds() dimension,
hence issue setupUI() from reshape() and not from init()
- GLButton: Using additional view-rotation like UISceneDemo01
- Multi-line text labels resize issues are
- Supposed sticky-edge is moving
(Sticky-edge are the opposites of the picked drag point)

UISceneDemo01 simply provides shape drag-move and -resize

Root package is 'com.jogamp.graph.ui.gl', i.e. a sub-package of Graph denoting UI and OpenGL usage.
Implementation will stay small, hence relative files size costs are minimal.
Source and build is in parallel to nativewindow, jogl and newt
and has a dependency to all of them.
The NEWT dependencies are merely the input listener ..

comparing the VisualID first; Added VisualIDHolder.isVisualIDSupported(VIDType)
We cannot accept 2 capabilities with different VisualID but same attributes otherwise accepted as equal,
since the underlying windowing system uniquely identifies them via their VisualID.
Such comparison is used in certail GLAutoDrawable implementations like AWT GLCanvas
to determine a configuration change etc.

Also tested w/ alternative JVM (Azul) .. works well, no big difference (but slower startup time, but might be OpenJDK 17->19 related as well).
Printing usual system infos to make the test record useful.

performance-hit measuring performance.
This was mostly notable on a Raspberry-Pi 4 arm64, where perfromance degragated around 3x using high-freq counter.
Using our well determined Clock.currentNanos() removes this overhead,
back to 'easy measuring' and having a well defined 'currentNanos()' since module start.
TestTextRendererNEWT00 can enable Region and Font perf-counter w/ '-perf',
w/o it only uses its own counter and hence reduce the high-freq burden (64% perf win on raspi4).
+++
Below numbers show that Region.addOutlineShape() perhaps needs a little performance work
to allow long text to be processed in 'real time' on embedded platform.
Hower, usually we cache the Region for long text and can have at least one liner
to be renderer within 60fps fast, i.e. Region produced in ~26ms for a 81 char line
instead of ~130ms for 664 chars.

newt.ws.mmwidth and newt.ws.mmheight property
This is essential on bare-metal devices where the screen DRM/GBM driver does not provide the screen-size (in mm).
Otherwise we would have resolution/(size_mm=0) infinity density and none of our graph font demos would work,
as we compute pixel-em-size based using dpi and pixel-pt-size.

Ease GLArrayData* buffer growth.
Using integer indices, i.e. GL_UNSIGNED_INT, requires us to pass a GLProfile 'hint' to the GLRegion ctor.
Region.max_indices is computed in this regard and used in Region.addOutlineShape().
TODO: If exceeding max_indices, the code path needs some work.
Buffer growth is eased via GLArrayData using its golden growth ratio
and manually triggering growth before processing all triangles in Region.addOutlineShape().
+++
TextRegionUtil static drawText() won't clear passed Region anymore, caller has to do this if so intended.

11), 5.* (Debian 12) and 6.* (Current Development trunk)
From here on, libav support has been dropped.
Required FFmpeg libraries to be fully matched by their major runtime- and compiletime-versions are:
- avcodec
- avformat
- avutil
- swresample
Library avdevice is optional and only used for video input devices (camera).
Library avresample has been removed, since FFmpeg dropped it as well in version 6.*
and swresample is preferred for lower versions.
The matching major-versions of each library to the FFmpeg version
is documented within FFMPEGMediaPlayer class API-doc.
Each implementation version uses the non-deprecated FFmpeg code-path
and compilation using matching header files is warning-free.

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.

- All pixelSize metrics methods are dropped in Font*
- TypecastGlyph.Advance dropped, i.e. dropping prescales glyph advance based on pixelSize

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)

(working state)
Both:
- Using Soft-PixelScale mode, i.e. converting all given window-units to pixel-units for native GDI/X11 ops
- Using scaled pixel-sized surface
- Adjusting NEWT's Monitor's window-unit viewport value to pixel-scale
For X11:
- Using global scale factor from environment variable, either: "GDK_SCALE", "QT_SCALE_FACTOR" or "SOFT_SCALE".
The latter is for testing only.
See https://wiki.archlinux.org/title/HiDPI
For Windows:
- Using actual monitor's pixel-scale via native SHC API (Shellscaling API, shcore.dll)
Misc:
- SurfaceScaleUtils.getGlobalPixelScaleEnv() reads a float value from given env names, first come, first serve
- MonitorModeProps.streamInMonitorDevice(..): Add `invscale_wuviewport` argument to scale wuvieport for soft-pixel-scale
- TestGearsNEWT: Enhance GL2 demo to be suitable for manual tests, this since my Windows KVM machine doesn't support ES2
- TestGLContextDrawableSwitch10NEWT: Add a few more test constraints .. working
Tested:
- Manually on a Windows virtual machine (KVM) using
- 2 virtualized 'Video QXL' cards and
- and 'remote-viewer' to see the 2 monitors
since `Virtual Machine Manager` build-in doesn't support
- remote-viewer spice://localhost:5917
- Manually on a Linux machine w/ SOFT_SCALE
- Both, X11 and Windows
- Place window on each monitor
- Move window across monitors w/ pixel-scale change (or not)
