feat(render): a geometry chunk emptied in place, the kind of its primitive told; a chunk gaining or losing its userdata gets a new buffer

Browse Source 
Erase() empties a chunk and keeps its handle to be filled again, for geometry made anew as it changes. Primitive() tells whether a chunk holds triangles or strips, -1 from a renderer which doesn't know. The VAO bank reused the buffer of a chunk of the same length even when the userdata came or went, the layout of the buffer differing then.
