Hide Behind

by Kaiochao
See through what you're hiding behind.

Demonstrates the use of image.override to fade out the trees that you're behind, where only you see the fade.

- Made the images per-client instead of per-hidden-object.
Should take up less memory overall; virtually zero memory when nothing is hidden.
Also lets us fade the image in and out over time.
- Updated demo to be easier to test with.
Thank you Kaiochao, more one great library that you make. I'm sure it will help many like me
I always wanted to implement something like Ter13's rooflib to some of my projects but never could get it to function properly with forum_account's sidescroller lib.

I'll see if I can get this to work though later today! thanks. =)
