Overview
Returns a string containing the source code to Allegro’s default vertex or pixel shader appropriate for the passed platform. The ALLEGRO_SHADER_AUTO value means GLSL is used if OpenGL is being used otherwise HLSL. ALLEGRO_SHADER_AUTO requires that there is a current display set on the calling thread. This function can return NULL if Allegro was built without support for shaders of the selected platform.
