Distorted Android

Make the Fragment effects truly 3D: change their 4D 'region' into a 3D 'center' (a point in 3D) and 3D 'region' (which is now a set of 3 radii defining an ellipsoid around the center)

Also corresponding changes to the applications.

Advances with the Earth app - prepare it to checking if any FRAGMENT or VERTEX effect correctly works on a Sphere mesh.

Redefine the Vertex Region from (x,y,r,unused) to (x,y,z,r). This takes into account the 'Z', which makes it possible to warp only one side of a 3D Mesh like Sphere.

Also corresponding changes in applications.

Improve the world map.

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.
