Distorted Android

Progress with the 'Earth' app.

Rename the old 'Cubes' app to 'Inflate' - this now combines the testing functionality of former 'Cubes' and 'Inflate' apps.
The old 'Inflate' in turn renamed to 'Earth' - here we are going to show an Earth rotating in space.

Make Matrix effects Rotate and Quaternion actually correct when it comes to the Z-axis. Also corresponding adjustments in apps.

Sphere: map the texture a bit better around the seam and the poles.

New texture showing the World (Mercator projection)

Do not let users choose a Mesh with cols or rows equal to 0.

Some fixes for Sphere; still not completely ok though.

Add support for MeshSphere (add ability to display it in the 'Effects3D' and 'Inflate' apps).
Still a bit buggy!

- new icon for the GLOW app
- rename the BitmapTree app to ObjectTree

Improve the Triblur app to be able to switch objects into 1 of 3 states: no postprocessing, blur, glow.
