From demo to proper code ;-)

Well, fixed the PIA setTransform(..) and it is what it is,
always quite sensitive when using the matrix for everything including zoom.
Plain and stupid basic stuff, I know.

The label (multiline text) needed to have origin 0/0 to work well w/
the build-in drag-zoom, all Shapes need.

OK, decoupled Shape from GraphShape, allowing non-graph stuff to be placed as well.
This also simplifies review, since Shape only contains the usual stuff (simple scenegraph if you must call it)
- lifecycle and locking/sync
- matrix ops

GraphShape details the Graph GLRegion handling.

Hence we can have a container of shapes in this regard, yes
- see it as a scenegraph node w/ build-in transformation node :)

Still, trying to keep it simple (KISS).

++++

All of the above was 'triggered' by the need to have a transformable container,
maybe having Graph Glyph's from a text to do something (type animation).
Now it can be used for anything.

So besides wasting my time with acquisition and paperwork,
I shall complete this container as well, then test on Raspi again.
Sort of a first finishing line.
