Setting up for X-Windows development on macOS

Yeah, X kind of works on MacOS, but the refresh/redraw rate in terminals is so bad that it is unusable for day to day work. I eventually had to stop trying and configure Iterm2 as a clunky rxvt-unicode simulacrum.

As a side note, the Xorg (XQuartz) distribution from MacPorts seemed to be more compatible with Xresources than the official XQuartz package.

I miss all aspects of Linux and I will shed a tear of joy when I can return to it on my work machine.
