Spent time just playing with child frames to get familiar with things. A 
few bugs I noticed:

There's something in the C code that makes this branch not work with the 
mini-frame package (https://github.com/muffinmad/emacs-mini-frame). The 
package works fine in graphical mode.

I'm using posframe for iteration. There's a minor thing where the cursor 
position is inconsistent when at the end of a line with a posframe on it 
in the tty. Maybe that's intentional? It's kinda confusing to me.

There's also a major thing where I can click on the child frame in the 
tty and then my cursor is actually in the child frame and I can just 
alter the text there. That behavior is inconsistent with the behavior on 
graphical displays and something I can investigate.
