I didn't do this; volunteers are welcome.

I fixed this. The problem was that w32_draw_rectangle wiped out what
was drawn inside it; I switched the order, so the box is drawn before
the glyphs inside it. Jason, could you please take a look and see if
I did everything right?
Assuming that on X the order doesn't matter (does it?), perhaps we
should switch the order there as well, for uniformity.

Not done; I have no idea how to do this.
In addition, I did this:
. renamed glyphless-char-control to glyphless-char-display-control
. renamed hexa-code to hex-code.
. changed TTY display top enclose U+nnnn and "empty box" displays in
"", to simulate a box and make the display easier to read.
. documented this feature in NEWS and in the manual.
There are a few issues with TTY display, see my other mail.
