R T _ S K E T C H _ P R E P

Given a pointer to a GED database record, and a transformation matrix, determine if this is a valid SKETCH, and if so, precompute various terms of the formula.

Returns - 0 SKETCH is OK !0 Error in description

Implicit return - A struct sketch_specific is created, and it's address is stored in stp->st_specific for use by sketch_shot().
