I think I've finally figured out what I want the core hierarchy to be.
Right now, it's just the two classes: View and Window (derived from
View). Window has a Group, and Group is just a collection of Views that
it manages. QwaqApplication is just an object but like a Window, it has
a Group of views.
View
Window has a Group
Group contains Views
QwaqApplication has a group
More work needs to be done on drawing and event handling, but things are
working again.
It doesn't work right now because View unconditionally sends refresh to
its textContext, but textContext can be a draw buffer which does not
respond to refresh. Still, these changes (notably the assignment chain
in qwaq-group.r really pushed qfcc).
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).
