// STEVE: MeshDeltas and/or MapDeltas lack the following clever features:
// - Realloc amounts: currently we realloc arrays with no extra room for growth (dv especially).

// These classes encompass the notion of a "Mesh Edit".  They are the principal means
// of keeping track of what's going on in the Edit Mesh modifier, and have many standard
// mesh edits available for use elsewhere.

// Principle is that, while these work as designed on the right mesh, they will give
// some result on the wrong mesh.

// Order of operations:
// Verts/TVerts/CVerts created or cloned.
// Faces created -- indices correspond to original vert list, then create, then clone.
// Face attributes & indices changed.
// Verts & faces deleted.

// "Channels" of data in MeshDelta -- different from PART_GEOM type channels!
