[x3d-public] SAIMatrix definition for X3D ECMAScript SAI standard

[Brutzman, Donald (Don) (CIV)]

As part of editorial revision of 19777-1, Dick and I found that X3D ECMAScript SAI standard was missing SAIMatrix definition.

Suggested definition follows - but we are ECMAScript users, not implementers.  Confirmation or improvement requested.

================
6.3.18 SAIMatrix

The data type is implemented as nested arrays of the numeric standard object type, with a total of either 9 elements (for a 3×3 matrix) or 16 elements (for a 4×4 matrix). Arrays are listed in column-major order, meaning that the outer array represents columns.
================

all the best, Don
