    42  * When using the "dynamic X11" functionality, we duplicate all the Xlib
    43  *  symbols that would be referenced by SDL inside of SDL itself.
    44  *  These duplicated symbols just serve as passthroughs to the functions
    45  *  in Xlib, that was dynamically loaded.
    46  *
    47  * This allows us to use Xlib as-is when linking against it directly, but
    48  *  also handles all the strange cases where there was code in the Xlib
    49  *  headers that may or may not exist or vary on a given platform.
