Request a RGB888 context, since SDL2’s default of RGB332 sucks.
On X11/GLX, it will select the first config available, that is the best
one, while on EGL it will iterate over them to select the one closest
to what the application requested.
Of course, anything lower than RGB888 looks bad and we really don’t
want that.
