Whitespace Trimming Issue

[joebfdn]

We are finally porting some things forward from the legacy Resizer lib to the Imageflow lib. It seems there is something wrong with the Imageflow whitespace trimming when applying percent_padding, or has the behavior intentionally changed? It seems trimming without percent_padding functions the same as before, so seems limited to when percent_padding is included. Below are 3 samples to illustrate.

It seems as if maybe it's taking the smallest pixel trim side, and subtracting that from the opposite side (i.e. if short side is X sub from Y) and then preserving the original smallest side? Sorry hard to explain, samples should show it well though.
