Detailed Description
C99 math shim with bj_real precision type and scalar utilities.
Column-major storage: elements are addressed as m[col][row].
Matrix utilities for 2D and 3D transforms using bj_real and bj_vec*.
Vectors are treated as column vectors and are multiplied on the right: res = M * v.
Provides creation, copy, transpose, arithmetic, products, inversion, orthonormalization, and common projection/viewport helpers for 3×3, 3×2, 4×4, 4×3.
