* It paints over the top-left corner of the terminal window. A little
floating window would be rather nicer and not much harder to do.
* It uses the low-memory global, DragHook, which is unavailable in Carbon
and broken in some versions of Mac OS 8 (8.5?). I suspect this is
unavoidable, though.

parts that haven't been painted yet still get an update event in their new
location. This code seems far too complicated, and I suspect there's a
better way. Still, scrolling continuously with the window partially
off-screen now works.

ignore when breaking text into runs for display, and implement setting this
on Mac (other ports just use 0xffffffff).
We don't use DeviceLoop for this any more because Apple Technical Q&A
QA1024 says we shouldn't. Unlike their example, we don't depend on the
Display Manager's being present either.

SetFractEnable unconditionally flushes the Font Manager's width cache,
and the default is fine for us anyway. This more or less doubles
redraw speed, which is nice, but still not really fast enough.

* No more mucking about with transfer modes. We always set up the foreground
and background sensibly, EraseRect the whole lot and use srcOr. Apple
Tech Note QD505 suggests that this should be faster than srcCopy.
* Always use the Palette Manager if we've got Color QuickDraw, even in 1bpp
modes.
* Apply the cursor colours _after_ all the other stuff, rather than trying to
get them through everything else intact.
Unfortunately, this doesn't make much difference to the speed.

background colour and pen mode have some silly effects on ScrollRect, so
set them back to their defaults before calling it.

(rather than straight to the backend), and then prod the terminal. I think
this is closer to the correct set of things to do.

This doesn't include any mkfiles.pl glue, and is missing one or two other
fixes. The terminal emulator is kind of working, though, as, I believe, is
the store module. Everything else is yet to be done.
