6b6b3261e5 UV: Improve UV Packer for non-square aspect ratios. 
When packing UVs on non-square materials, care must be taken when
rotating to maintain the original aspect ratio.

In this change:
 * Improve packing efficiency on non-square materials.
 * Add aspect ratio in UV Packing API.
 * Add output angle to UV Packing API for future use.

This seems fine, prefer not to add angle though (can be added when it's used).

I don't think we should be adding members for future use, add them as part of implementing the functionality. Doing so risks leaving in unused things in the API.

But also, it makes it hard to review the correctness of the next pull request that actually uses it, or where the conclusion may be this is not the correct approach.

What is the meaning of the squared aspect ratio here? Deserves a comment if this is correct.

Don't add twitter links in Blender code, you can mention it in the pull request description instead.
