The conditional selector performance seems to work nicely, but I've
found a mistake with View.window (partly, realizing why my old lib (and
probably TV in the first place) had separate textContext and buffers
between views and groups).
Doesn't have timestamps at this stage, but otherwise it reflects the
event system I had in my old text UI which was heavily based on
TurboVision. TV is pretty good (after looking at things a bit closer I
found it wasn't as deep as I thought), and better yet, Borland released
it to the public domain 23 years ago! (wish I'd known that).
Anyway, this commit gets something happening on the screen, even though
the current hierarchy is still a mess.
This is horrible, doesn't work, isn't really the direction I want to go
(that became apparent while implementing Screen's handleEvent) and
crashes anyway (Array and not-id...)
*sigh*
Still, this does have some good stuff in it, and it pushed qfcc along
some more.
