SimpleSineSynth Button and have MediaButton to produce mono-only for 3D sound
- Move SimpleSineSynth and MediaPlayer around for spatial 3D sound
- Shape's center is the Source position
- SimpleSineSynth controlls:
- click to enable
- scroll vertical -> frequency change
- scroll vertical + ctrl-key -> volume/amplitude change

addShapeToRegion() impl to utilize OutlineShape -> GLRegion ctor w/ proper buffer-size
This way we avoid unnecessary buffer growth and allow creation of 'always' fitting buffer sizes.
+++
Update or freshly create the GLRegion, while allocating its buffers with given initial `vertexCount` and `indexCount`.
Method shall be invoked by the addShapeToRegion(GLProfile, GL2ES2) implementation before actually adding the OutlineShape to the GLRegion.
addShapeToRegion(GLProfile, GL2ES2) is capable to determine initial `vertexCount` and `indexCount` buffer sizes,
as it composes the OutlineShapes to be added.
updateGLRegion(GLProfile, GL2ES2, TextureSequence, OutlineShape) maybe used for convenience.
In case GLRegion is `null`, a new instance is being created.
In case the GLRegion already exists, it will be either cleared if the GL2ES2 `gl` instance is not `null`
or earmarked for deletion at a later time and a new instance is being created.

this enhances code readability, simplifies API, reduces bugs and may improve performance.

UISceneDemo20 with button Groups
All layout magic is simply performed in Group.Layout.layout(..) @ validate, incl. updating the
bounding box to have the padding included.
This demonstrates GraphUI's capability to be used with correct layout,
i.e. its pure matrix based position, scale and rotation.

invPMv null; PMVMatrix: Make Mvi, Mvit optional at ctor, add user PMv and PMvi - used at gluUnProject() ..
Matrix4f.mapWin*() variants w/ invPMv don't need temp matrices,
they also shall handle null invPMv -> return false to streamline usage w/ PMVMatrix if inversion failed.
PMVMatrix adds user space common premultiplies Pmv and Pmvi on demand like Frustum.
These are commonly required for e.g. gluUnProject(..)/mapWinToObj(..)
and might benefit from caching if stack is maintained and no modification occured.
PMVMatrix now has the shader related Mvi and Mvit optional at construction(!), so its backing buffers.
This reduces footprint for other use cases.
The 2nd temp matrix is also on-demand, to reduce footprint for certain use cases.
Removed public access to temporary storage.
+++
While these additional matrices are on demand and/or at request @ ctor,
general memory footprint is reduced per default and hence deemed acceptable
while still having PMVMatrix acting as a core flexible matrix provider.

as well as getSurfaceSize(..) (use absolute size)

Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*)
Big Easter Cleanup
- Net -214 lines of code, despite new classes.
- GLUniformData buffer can be synced w/ underlying data via SyncAction/SyncBuffer, e.g. SyncMatrix4f + SyncMatrices4f
- PMVMatrix rewrite using Matrix4f and providing SyncMatrix4f/Matrices4f to sync w/ GLUniformData
- Additional SyncMatrix4f16 + SyncMatrices4f16 covering Matrix4f sync w/ GLUniformData w/o PMVMatrix
- Utilize Vec3f, Recti, .. throughout API (Matrix4f, AABBox, .. Graph*)
- Moved FloatUtil -> Matrix4f, kept a few basic matrix ops for ProjectFloat
- Most, if not all, float[] and int[] should have been moved to proper classes
- int[] -> Recti for viewport rectangle
- Matrix4f and PMVMatrix is covered by math unit tests (as was FloatUtil before) -> save
Passed all unit tests on AMD64 GNU/Linux

traversing the PMVMatrix throughout childs (-> see TreeTool).
Utilizing the Vec*f (and Matrix4f) API w/ AABBox et al renders our code more clean & safe,
see commit 15e60161787224e85172685f74dc0ac195969b51.
A Group allows to contain multiple Shapes,
hence the PMVMatrix must be traversed accordingly using TreeTool
for all operations (draw, picking, win->obj coordinates, ..).
Hence Scene + Group are now implementing Container
and reuse code via TreeTool and a Shape.Visitor*.
This will allow further simplification of user code.

Ray, AABBox, Frustum, Stereo*, ... adding hook to PMVMatrix
Motivation was to simplify matrix + vector math usage, ease review and avoid usage bugs.
Matrix4f implementation uses dedicated float fields instead of an array.
Performance didn't increase much,
as JVM >= 11(?) has some optimizations to drop the array bounds check.
AMD64 + OpenJDK17
- Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest)
- Matrix4f.mul(b) roughly ~3% slower than FloatUtil.multMatrix(a, b, dest)
- FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all
- Matrix4f.invert(..) roughly ~3% slower than FloatUtil.invertMatrix(..)
RaspberryPi 4b aarch64 + OpenJDK17
- Matrix4f.mul(a, b) got a roughly ~10% enhancement over FloatUtil.multMatrix(a, b, dest)
- Matrix4f.mul(b) roughly ~20% slower than FloatUtil.multMatrix(a, b)
- FloatUtil.multMatrix(a, a_off, b, b_off, dest) is considerable slower than all
- Matrix4f.invert(..) roughly ~4% slower than FloatUtil.invertMatrix(..)
Conclusion
- Matrix4f.mul(b) needs to be revised (esp for aarch64)
- Matrix4f.invert(..) should also not be slower ..

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.
