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.

Minor simplifications in Mesh.

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....

Some simplifications in Meshes. Hide stuff inside MeshBase.

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

Small things.

Move EffectMessageSender to the 'message' package (duh!)

Rename MeshObject to MeshBase.

Fully move the Meshes to their own package.
