Revision 7a5e538a

Added by Leszek Koltunski over 5 years ago

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.
