Expand description
Builds a program depending on the GLSL version supported by the backend.
This is implemented with successive calls to is_glsl_version_supported().
Returns a glium::program::ProgramChooserCreationError.

# #[macro_use]
# extern crate glium;
# fn main() {
# let display: glium::Display = unsafe { std::mem::uninitialized() };
