Progress with any depth MeshCubes.

Change of API in anticipation for MeshCubes of any depth (currently only 0 and 1 work)

Progress with Stencil app. Rendering through an intermediate FBO still doesn't quite work.

First try to convert the Stencil app to a dual (directly to Screen / through intermediate Framebuffer) mode.
Doesn't work yet ( API is inconvenient / plain wrong )

Add possibility to create FBOs with combined DEPTH/STENCIL.

Simplify setting up DistortedScreen.

1. Correct some bugs in DistortedRenderState
2. Thus make the Stencil App work
3. New icon for it

Progress with Stencil App; should be working now AFAIK but doesn't.
