* Constraints Graph Notes

|

* For constraints, we currently only add a operation node to the Transform
|
|
* or Bone components (depending on whichever type of owner we have).
|
|
* This represents the entire constraints stack, which is for now just
|
|
* executed as a single monolithic block. At least initially, this should
|
|
* be sufficient for ensuring that the porting/refactoring process remains
|
|
* manageable.
|
|
*
|
|
* However, when the time comes for developing "node-based" constraints,
|
|
* we'll need to split this up into pre/post nodes for "constraint stack
|
|
* evaluation" + operation nodes for each constraint (i.e. the contents
|
|
* of the loop body used in the current "solve_constraints()" operation).
