UIPolyMask/Crop Feature

As a Roblox developer, it is currently too hard to get clean UI elements with compression of images. Using what is already in Studio would save a lot of time.

If this issue is addressed, it would improve development experience because it would allow myself and other developers to be more creative with Frames as more a powerful tool, rather than just another object of the many UI objects we have at our disposal.

The feature would consist of multiple handles to crop/mask from different angles.

I liked the UICorner update, so I am trying to keep the magic going!
