In principle, there should not be many modifications in the X interface,
apart from a few pending bugfixes. The only thing we might do in
the future is adding some new widgets (without incidence for you) and
implement the TMGUI abstraction (which will mainly reorganize
the directory structure and maybe necessitate one level of abstraction).

In the main event loop, repainting is done only when there are no more
pending events. You may put some "cout<<" statements in the event loop
in order to know which events are pending when starting up.
I guess that there will be some invalidate-region events pending.

Necessarily yes: we repaint only the regions which are in a list
of invalid rectangles. I actually planned to perform some simplifications
in this list in order to merge adjacent regions together.

Cool.

In fact, did you try to build some of the programs in TeXmacs-misc?
See the files TeXmacs-*-misc.tar.gz on ftp://ftp.texmacs.org/pub/TeXmacs/misc
This will allow you to check whether the things you have done so far
are working on some examples of lesser complexity.
