.SH DESCRIPTION
.PP
Returns a string containing the source code to Allegro\[cq]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.
