[Feature request] Maintain Aspect Ratio when resizing

[TanakJuka]

Hi,
I've been using AltSnap daily since I discovered it forked from the abandoned AltDrag.

Lately I've been using it a lot to Resize windows but end up unable to keep their Aspect Ratio - For now I've added a workaround by using Sizer (found it in the "feature that won't be implemented soon" section, reasonably).

Still, Sizer isn't as immediate as a resizer as I'd like, so here's the feature request:

Is it possible to add a feature that only resizes windows by keeping their aspect ratio?
I'm not picky in the way it might activate, I though of:

• Having a special fancy zone that takes up x% by x% of the lower right window (to use with the already active Resize), that only resizes with AR intact
• Using a modifier key when drag-resizing (might conflict with other modifiers active, I'd imagine)
• Having a different action from Resize, activated with a different mouse button, like "ResizeWithAR"
  But I'd guess any other way would work for me. I imagine that maintaining aspect ratio means the drag cannot be smooth but has to go in steps (like, for 16:9 it only resizes after the drag action goes through EITHER 9 pixel of height or 16 pixels of width)

I have no clue how easy or hard it would be to implement, and I'm not really sure how valuable a feature you'd feel it is, but I'm available to test it if needed!

To the extent of my knowledge, this isn't already present in AltSnap. If it is... just point me to it, and I'll manage the penance whipping.

Thanks in advance, and in either way this request goes!
