SYNOPSIS
#include <allegro5/allegro.h>
void al_build_transform(ALLEGRO_TRANSFORM *trans, float x, float y,
float sx, float sy, float theta)
DESCRIPTION
Builds a transformation given some parameters. This call is equivalent
to calling the transformations in this order: make identity, scale,
rotate, translate. This method is faster, however, than actually call‐
ing those functions.
Parameters:
· trans - Transformation to alter
· x, y - Translation
· sx, sy - Scale
· theta - Rotation angle in radians
