al_compose_transform - Allegro 5 API
.SH SYNOPSIS

\f[C]
#include <allegro5/allegro.h>

void al_compose_transform(ALLEGRO_TRANSFORM *trans, const ALLEGRO_TRANSFORM *other)
\f[R]
.fi
.SH DESCRIPTION
.PP
Compose (combine) two transformations by a matrix multiplication.
.IP
.nf
\f[C]
trans := trans other
\f[R]
.fi
.PP
Note that the order of matrix multiplications is important.
The effect of applying the combined transform will be as if first
applying \f[V]trans\f[R] and then applying \f[V]other\f[R] and not the
other way around.
.PP
\f[I]Parameters:\f[R]
.IP \[bu] 2
trans - Transformation to alter

other - Transformation used to transform \f[V]trans\f[R]
