libgdiplus bundled with official mono release is missing X11 support on Mac

[QianNangong]

GdipCreateFromXDrawable_linux is only available when both cario and libgdiplus are built with X11 support, however it is not included in the latest package.

Gtk not found (missing LD_LIBRARY_PATH to libgtk-x11-2.0.so.0?), using built-in colorscheme

That is intentional. Apple no longer supports the X11 server and the libraries shipped with it are notoriously outdated. Most importantly it gets problematic because it ships its own version of Cairo that collides with any newer version installed by Homebrew.
