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.

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 computation of the thickness of the postprocessing halo - should be independent of the size of underlying object now.
Still it is not completely ok, it appears to depend on the ModelView matrix (use the Effects3D app to rotate the object around Z-axis to see this)

Make the Effects3D app a bit more user-friendly.

Progress with Inflate (building block of postprocessing effects: the proper way of marking a halo around a Mesh)
'Inflate' app testing the machanism. MeshFlat appears to be working, now we only need to fill up the per-vertex Inflate vector in the MeshCubes.

Added a new attribute to vertices of a MeshBase object: the vec3 'inflate' vector.
This vector describes the direction where the vertex needs to be moved when we 'inflate' the whole mesh.
If the mesh is locally smooth, this is simply the normal vector; otherwise (for example in the corners of the MeshCubes) - not....

Fix the preprocess shader. This makes the 'Postprocess Tree' app look good again.

Progress with thr Glow effect - moving glow app looks ok now.

Progress with a more generic 'preprocess' stage of Postprocessing Effects.

Hide the FBO_QUEUE thing inside the library. The queue is running internally now, without public setAsOutputFBO() thing (simplifies writing postprocess effects)
