NAME

       al_use_shader - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              bool al_use_shader(ALLEGRO_SHADER *shader)

DESCRIPTION

       Uses the shader for subsequent drawing operations on the current target bitmap.  Pass NULL
       to stop using any shader on the current target bitmap.

       Returns true on success.  Otherwise returns false, e.g. because the shader is incompatible
       with the target bitmap.
