#71678: gpredict: Crash with GDK error when closing a window when the render
extension is disabled in Xquartz.

--------------------+----------------------
 gpredict suffers from the same render transparency issue with xquartz that
 many other programs have.  Setting `defaults write org.xquartz.X11
 enable_render_extension 0` fixes that, but when you do it now crashes with
 a GDK-Error whenever you close a window with the program.

 The error message is;
 {{{
 (gpredict:86166): Gdk-ERROR **: 15:46:59.951: The program 'gpredict'
 received an X Window System error.
 This probably reflects a bug in the program.
 The error was 'BadLength (poly request too large or internal Xlib length
 erro'.
   (Details: serial 1635 error_code 16 request_code 72 (core protocol)
 minor_code 0)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the GDK_SYNCHRONIZE environment
    variable to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error()
 function.)
 zsh: trace trap  gpredict
 }}}

 Setting `enable_render_extension 1` (the original default) stops the
 crash, but it then has the black screen/transparency issue again.  This
 makes gpredict functionally useless.

 Interestingly, if I manually compile gpredict and run it from the src/
 directory, with `enable_render-extension 0` it works, however if I install
 it into `/usr/local/` and run it, it crashes in exactly the same way.

 I have removed all configs and ran it as new, and it crashes as well.

 This is on a M1 Max MacBook Pro under Sequoia, 15.2, MacPorts 2.10.5.
