"""
Create the route to compute the output transform for the avar.
This is done using node 'stacks' which allow multiple contribution from being added while still
be 'clear' for the rigger which layer is providing which input.
By keeping stack seperated, we are able to keep them in isolation and use the 'worldMatrix' of their
leaf to easily compute the total contribution.
This would result in the following matrix multiplications:
1) 'offset group'
We start with the bind transform.
The resulting matrix is in local (also known as pre-deform) space.
3) 'avar stack'
This compute the desired movement from the avar values.
Being a stack, it can be modified after creation if needed by adding layers to it.
The resulting matrix is still in local space.
4) 'post avar' stack'
This add any contribution needed after the avar.
Being a stack, it can be modified after creation if needed by adding layers to it.
Ex: Used for having the 'all' macro avar influence other avars.
The resulting matrix is still in local space.
5) 'parent' group
This matrix is identity at bind pose and will add the movement from the parent of the avar.
The resulting matrix is in world space.
The final transform is computed by multiplying all these stacks togheter:
- offset.matrix
- pre-avar.worldMatrix
- avar.worldMatrix.
- post-avar.worldMatrix
- parent.matrix
