Overview
Sets the refresh rate to use when creating new displays on the calling thread. If the refresh rate is not available, al_create_display(3) will fail. A list of modes with refresh rates can be found with al_get_num_display_modes(3) and al_get_display_mode(3).
The default setting is zero (don’t care).
