Add ScrollType BOTTOM and TOGGLE for BufferView::scrollToCursor()
BOTTOM shows the paragraph containing the cursor at the bottom of the
work area.
TOGGLE does CENTER, then TOP, BOTTOM and finally cycles to CENTER.
This is a feature copied from emacs's C-l binding.
Add new argument "caret" to lfun "scroll" that can be used like
scroll caret center
Change the keys (either C-l, M-l or F5) bound to screen-recenter to
"scroll caret toggle".
As an experiment, change paragraph-goto to use this scrolling method.
This can be tested when going to a heading in the outline pane.
Dear all,
These two last changes are the whole point of this commit, and part of
the motivation of my recent work on scrolling. This is stolen from
emacs: the binding F5 (cua), M-l (mac) or C-l (emacs) now puts caret at
center as expected, but, when repeated, it now goes to top and then bottom.
This a very good tool IMO to see the context around an element. I use it
for code.
Then, I changed the outline to yield the same effect. I expect some of
you to hate it, but discussion is good and this is not the final design.
Again, clicking several times on an element shows what is below it,
around it, and so forth.
I also noticed several weird things:
* when aligning to top, only the top level paragraph is taken into
account. If I have a large branch with headings in it, the code will try
to show the branch in full and otherwise the heading will be at the
bottom. What's the point of doing that?
* the same happens with an equation in a possibly large paragraph. The
priority is to put the paragraph first.
* there is some ad-hoc code that adds twice the height of a typical row
before the paragraph. In passing, this means that a tall row (Chapter)
will be barely shown completely. I remember that changing that has met
resistance and I had to revert it. How is this useful to you?
