Re: [AD] al_get_opengl_version design flaw?

[Trent Gamblin <trent@xxxxxxxxxx>]

Ok, after considering everything, I think the best option is to have a
new function "al_get_opengl_variant()" that will return whether the
device uses regular gl or gles.. so the user can test it before creating
a display. I'll add it before the RC.
