Drawings can't be drawn partially, which sometimes makes things jerky.

beginning of a new approach to scroll+wrap

So far I've just changed how existing variables are organized, and put
some scaffolding in place for dealing with the new types. Next up:
rewriting the code for scrolling to something that feels more obviously
correct.

some more logging

Still lots of signs it's all messed up, but I can't be sure until I
bring all the other keyboard shortcuts in sync.
I just need a better data structure that simplifies the logic. Perhaps
talk in terms of screen lines. In which case:
We'll need to convert lines to screen lines at some point.
We'll need to fix up screen lines when inserting and deleting
characters.

I'd wrapped currx in two conditionals, and not noticed that it gets
reclaimed within the other.
The hint is clearly more work than it's worth. Just take it out.

Manual test used here:
abc

def

Hitting page-down moves the cursor from abc to ghi. The 'ghi' line
should be fully visible on screen.

if you have a long series of drawings without intervening lines of text
you won't be able to scroll through them all.
