Distorted Android

Convert Projection to not use the depreciated MeshBase.setStretch() API.

Correct the Rubik app for the recent changes to the library's Node.

Size of the FBO internal to Nodes is now NO MORE taken from the Mesh's stretch values.
Instead, the size is copied from child's FBO size (if there is one) or if the child is a leaf with texture in it (which is sizeless) then we get the default 100x100 ( which means we probably have to explicitly call Node.resizeFBO() )

Minor.

Remove width & height from InternalSurface and move it to InternalOutputSurface.

Hide the InternalSurface class inside its package.

Minor.

Convert RubikCube to the new V&F center schema!

Moving the Vertex and Fragment centers of effect to the center of the Mesh.

Fixes for the merge.
