The process is: * A TOOL creates a GRID_HELPER * Optionally, it pre-loads a "persistent" batch of construction geometry (e.g. for an item's original position) * The grid helper finds useful snap 'anchors' as before, including those involving the construction items. * Other items on the board can be 'activated' by snapping to one of their main points. Then, if it has construction geometry, it will be added to the display. At most 2 items of this kind of geometry are shown, plus the original item, to reduce avoid too much clutter. The dashed snap lines state machine is also handled in the CONSTRUCTION_MANAGER and displayed in the CONSTRUCTION_GEOM item.	1 year ago

Snapping: Add construction geometry snapping

This is a pretty major rework of the snapping system.
The GRID_HELPERs now have a separate CONSTRUCTION_MANAGER
which handles some of the state involving "construction
geometry".

This is fed with 'extended' geometry (e.g. "infinite" lines from
segments) for use in generating things like intersection points.
It also handles adding this geoemtry to a GAL view item
(CONSTRUCTION_GEOM) for display to the user.

The process is:

* A TOOL creates a GRID_HELPER
* Optionally, it pre-loads a "persistent" batch of construction
  geometry (e.g. for an item's original position)
* The grid helper finds useful snap 'anchors' as before, including
  those involving the construction items.
* Other items on the board can be 'activated' by snapping to one
  of their main points. Then, if it has construction geometry,
  it will be added to the display. At most 2 items of this kind of
  geometry are shown, plus the original item, to reduce avoid
  too much clutter.

The dashed snap lines state machine is also handled in the
CONSTRUCTION_MANAGER and displayed in the CONSTRUCTION_GEOM item.
