c1e11f699e X11: Provide specific X error when SDL_GL_CreateContext fails. 
This makes the X error handler used for GL context creation handle *all* errors
and provide the user with specific error messages when SDL_GL_CreateContext
fails.

dd5277d65c Fixed stack overflow in X11_CreateWindow() (thanks, rapha and Brad!). 
This should be a "long" which on a 64-bit system is likely to be > 32-bits,
 causing XGetICValues() to write past the end of the variable (and stack).

Fixes Bugzilla #2513.

Someone provided a patch for this, recently on the mailing list :
-----

Hi,

it is possible to skip the bug in libX11 by using the defaults for
XNResourceName and XNResourceClass in `XCreateIC' (the table for the
"Input Context Values" [1] in libX11-doc shows that a default is
provided if it is not set).

f6953cf4c2 Fixed bug 2502 - Memory leak inside SDL_x11events.c -> X11_DispatchEvent(_THIS) 
bojko_1000

Code @566:
            if (data->xwindow) {
                Atom _net_frame_extents = X11_XInternAtom(display, "_NET_FRAME_EXTENTS", 0);
                Atom type = None;
                int format;
                unsigned long nitems = 0, bytes_after;
                unsigned char *property;
                X11_XGetWindowProperty(display, data->xwindow,
                    _net_frame_extents, 0, 16, 0,
                    XA_CARDINAL, &type, &format,
                    &nitems, &bytes_after, &property);

                if (type != None && nitems == 4)
                {
                    border_left = ((long*)property)[0];
                    border_right = ((long*)property)[1];
                    border_top = ((long*)property)[2];
                    border_bottom = ((long*)property)[3];
                }
            }

Code after _the fix_:
            if (data->xwindow) {
                Atom _net_frame_extents = X11_XInternAtom(display, "_NET_FRAME_EXTENTS", 0);
                Atom type = None;
                int format;
                unsigned long nitems = 0, bytes_after;
                unsigned char *property;
                X11_XGetWindowProperty(display, data->xwindow,
                    _net_frame_extents, 0, 16, 0,
                    XA_CARDINAL, &type, &format,
                    &nitems, &bytes_after, &property);

                if (type != None && nitems == 4)
                {
                    border_left = ((long*)property)[0];
                    border_right = ((long*)property)[1];
                    border_top = ((long*)property)[2];
                    border_bottom = ((long*)property)[3];
                }
                X11_XFree(property);
            }

I have found that leak with valgrind.
