found moving verts in pythons 2.5 api is approx 10x slower because the multi-dimensional array assignment reads the array 3 times (typecheck, length-check & for-real).

the length check was running sequence checks on every number which would fail, small speedup by avoiding this.

should eventually get this working faster by reading once into an allocated array.
