void al_compose_transform(ALLEGRO_TRANSFORM *trans, const ALLEGRO_TRANSFORM *other)
.EE
.SH DESCRIPTION
Compose (combine) two transformations by a matrix multiplication.
.IP
.EX
trans := trans other
.EE
.PP
Note that the order of matrix multiplications is important.
The effect of applying the combined transform will be as if first
applying \f[CR]trans\f[R] and then applying \f[CR]other\f[R] and not the
other way around.
