Answer 1

None of the anchor declarations include values for the anchor orientation, for instance

anchor: [
  [1, 0.23, 0, 0]
],

this one, being on the right near the top edge, probably should start out moving to the right horizontally, so:

anchor: [
  [1, 0.23, 1, 0]
],

whereas this one, on the left, should start moving horizontally to the left:

anchor: [
  [0, 0.23, 0, 0]
],

so:

anchor: [
  [0, 0.23, -1, 0]
],

a similar consideration needs to be made for the other anchors. the value at index 3 is for the y axis.
