[orca-list] Update on (work-in-progress) presentation of selection changes in Calc

[Joanmarie Diggs <jdiggs igalia com>]

Hey all.

Having Orca present selection changes in Calc is now something I'm
actively working on. I just committed a change to present when entire
rows and or columns get selected or unselected. Mind you, this
functionality assumes that Calc tells us. It doesn't always. Here's one
instance which I can reproduce reliably:
https://bugs.documentfoundation.org/show_bug.cgi?id=118508. It needs to
be fixed in LibreOffice; not Orca.

I'm also noticing that during selection, the accessible object for the
cell you're in sometimes becomes a zombie. So if you cancel selection,
Orca might give you more details about the table than you'd like.
LibreOffice/Calc should not be destroying objects on us like that. I
still need to come up with a reliable test case. When I do, I'll file
that one as well against LibreOffice.

I have also made progress on -- but not yet committed -- presenting
simple selection changes. There are some associated performance issues
I'm still working on to get this right. With any luck, I'll finish that
tomorrow and commit it.

Stay tuned!
