WELL! :^D I wondered how mine could have been _so_ many revisions
(35!?) out-of-date, considering my distro is only 2 years out-of-date,
and SDL2 has been around forever. :-D

I supposed, based on this, that we could simply call this a
known-issue, but I don't really think it's worth trying to address it.
In other words: recommend people _not_ use the SDL1.2 version of Tux
Paint with an SDL12-compat, and instead just use the SDL2.0 versions
of Tux Paint directly.

Any objections?  If not, I can close those two tickets, and put
a not somewhere on the website (to at least keep track of it,
I'm thinking https://tuxpaint.org/requirements/ ... rather than
the actual "known issues" page, https://tuxpaint.org/docs/known_issues/,
because we'd need to keep it around 'forever', and I'd rather not
clutter it up too much...)

Thanks!
