TGLLogicalShape
Abstract logical shape - a GL 'drawable' - base for all shapes -
faceset sphere etc. Logical shapes are a unique piece of geometry,
described in it's local frame - e.g if we have three spheres in :
Sphere A - Radius r1, center v1
Sphere B - Radius r2, center v2
Sphere C - Radius r1, center v3
Spheres A and C can share a common logical sphere of radius r1 - and
place them with two physicals with translations of v1 & v2. Sphere B
requires a different logical (radius r2), placed with physical with
translation v2.
Physical shapes know about and can share logicals. Logicals do not
about (aside from reference counting) physicals or share them.
This sharing of logical shapes greatly reduces memory consumption and
scene (re)build times in typical detector geometries which have many
repeated objects placements.
TGLLogicalShapes have reference counting, performed by the client
physical shapes which are using it.
See base/src/TVirtualViewer3D for description of common external 3D
viewer architecture and how external viewer clients use it.

void InvokeContextMenu(TContextMenu & menu, UInt_t x, UInt_t y) const
Invoke popup menu or our bound external TObject (if any), using passed
'menu' object, at location 'x' 'y'
