No Mask/Clipping Support for Spines?

Hey hey,

I was looking at the examples of spine-runtimes and found this clipping example of applying a mask to spine objects.

When I tried applying this to space boy in playcanvas, I got a lot of errors. After some searching through the spine.min.js you provide, I couldn’t find the functionality for clipping spine objects. I was wondering why that is, and if you plan on adding this feature in the future?
