RNA
* Mesh.add_geometry, Mesh.update and make indices editable. This
is without checking if they are valid still, no time now to
implement this.
* Also fix warnings in rna_ui.c, and a bug in CDDM_calc_edges.
Example code:
co = [0.0, 0.0, 0.0] + [1.0, 0.0, 0.0] + [0.0, 1.0, 0.0] + [1.0, 1.0, 0.0]
faces = [0, 1, 2, 0] + [1, 3, 2, 0]
mesh.add_geometry(4, 0, 2)
mesh.verts.foreach_set("co", co)
mesh.faces.foreach_set("verts", faces)
mesh.update()
