Fixes https://github.com/fonttools/fonttools/issues/1556 When a component uses firstPt/secondPt reference anchor points instead of XY offsets, and the component also has a transform, fonttools is incorrectly computing its bounding box. This is because we are computing the translation offset between firstPt and secondPt before applying the 2x2 scale/rotation/shear transform. By the time we do the translation, the offset is now incorrect. We need to compute the translation offset after we have applied the 2x2 transform.
