Fix scale/translation for fixed rotation PiP enter

Make sure we are properly manipulating the leash during
swipe PiP to home with fixed rotation, by scaling until
the first edge matches the target bounds.

Also make sure to adjust the translation in the proper direction
for cases that involve rotation of the leash from either
ROTATION_90 or ROTATION_270.

These manipulations are also made sure to match those done in Shell
at the jumpcut (TRANSIT_PIP), when the launcher animation is at
fraction=1.0.
