NAME
       qscale_matrix, qscale_matrix_f - Optimised routine for scaling an already generated matrix. Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       void qscale_matrix(MATRIX *m, fixed scale);

       void qscale_matrix_f(MATRIX_f *m, float scale);

DESCRIPTION
       Optimised routine for scaling an already generated matrix: this simply adds in the scale factor, so there is no need to build two temporary
       matrices and then multiply them together.
