Magic Cube

Create the 3 Popups only on first button click - this time we can have the final screen dimensions (and also it starts faster ) Before we weree getting the screen size from before hiding navigation bars, which made the height smaller, which made the number of obejcts and levels in the popups sometimes too small!

Progress with cuboids.

Fix the Solver

make numLayers into an int[] (preparation for Cuboids)
Caution: because of previous changes to cubit order in cube, the Solver is broken!

'IconMode' finished.

Remove unneeded API.

Relax objectlib's requirements: it can be displayed not only on top of a DistortedScreen, but any DistortedFramebuffer.

Simplification

Use the off-center objects to display the object in Tutorial mode properly.
Now it is not covered by the right bar!

Remove the 'setupObject()' redundant API.
