    50  * When using the "dynamic X11" functionality, we duplicate all the Xlib
    51  *  symbols that would be referenced by SDL inside of SDL itself.
    52  *  These duplicated symbols just serve as passthroughs to the functions
    53  *  in Xlib, that was dynamically loaded.
    54  *
    55  * This allows us to use Xlib as-is when linking against it directly, but
    56  *  also handles all the strange cases where there was code in the Xlib
    57  *  headers that may or may not exist or vary on a given platform.
