GeometricObject

Each geometric objects has several update functions, here they are:

1. updateGeometry(movedPoint) must be called after any child point is changed (i.e. line's endpoint or arc's center was moved) recalculates inner parameters of the geometry (if present, i.e. center, angles)
2. updateSizes(owningView) must be called after camera or object has changed, and after any geometrical changes recalculates any required sizing data (i.e. width value) automatically generated by mixinPixelSizedGeometry
3. updateVisualization() must be called after anything changes, which may influence visible representation of object updates or rebuilds a THREE.Mesh which visibly represent the object Note that each update function depends on the data obtained from the previous steps.

Here is general advice of how to call update functions:

• call updateGeometry directly and only inside controls handlers (when smth is edited)
• do not call other updates directly, just register each object with Sketcher.registerVisualization
