[Feature Request] Enhance opposite-planar

[alanOracle]

Is your feature request related to a problem? Please describe.
opposite-planar resize option is not working properly.

• It should be able to support cross axis editing
• If you move rapidly a coordinate while on this mode you can get out of the allowed 'zone' (pointerDistance)
• having minDistanceFromSelectionPoint significantly affects the UX the user should not notice theres a "jump" when it gets closer to the origin

Describe your proposed idea for the solution to this problem

• By adding a new method similar to scalePlanar but with invertX an invertY parameters should be possible to accomplish cross axis.
• To calculate if a user wants to cross an axis we could simply check if the selectedFeature is in one side of the axis and at the same time the cursor is in the other side of the axis
• We should not limit events to be within the range of pointerDistance since if the user moves fast it could get out of that range.

The proposed solution works on opposite-planar but i think it could be slightly modified to work also on center-planar

Hey @alanOracle - thanks for raising. I agree resizeable isn't quite where I want it to be UX wise at the moment. I just wanted to get something out that mostly worked but appreciate it's still a bit buggy. It is coming and I will work on these suggestions, I'll let you know when it's up to scratch! Appreciate the PR for this, but unfortunately I can't accept with the Oracle copyright notice, hope you understand.
