Distorted Android

Rename MeshObject to MeshBase.

Fully move the Meshes to their own package.

Convert everythig to GLES31 (there were some GLES30 remnants)

Stencil App: Do not request any special EGL config; with DistortedScreen now buffered, we don't have to (and in fact this config doesn't exist on HTC Desire 12)

Minor.

Move all the knowledge about Vertex and Fragment effects to their respective classes.

Change of API: move setting the EGL context back to the APP.

Further progress with Apps: 28 (out of 31) compile now.

Further progress with Apps: 18 (out of 30) compile now.

Progress with support for Effect classes.

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

Minor

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 )

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.

Beginnings of Stencil App.
