Caching Vectors for Rendering in the Canvas

[Fancy2209]

#1121 and #1123 finally added the ability of drawing trough Vectors instead of Textures, but there is one problem with this, tesselating complex shapes is slow.

I am opening this issue because we should have a way to store Pretesselated Vectors, that can just be loaded from a file instead of having to tesselate everything when you want to draw them, not sure what the best way to implement this would be though.

I added the "Feature" flag because I can see that need for that functionality. 👍 I'm afraid that's about all I can do right now to help, though. 😆
