[Tuxmath-devel] tuxmath/t4k_common patches

[LM <lm...@gm...>]

I'm reposting here in case someone's not on the tux4kids-discuss list.

I can't say that I'm finished patching yet, but I'm at a point where
I'm testing and looking for any bugs to fix.  I have tuxmath building
with SDL2.  I fixed several issues where the program crashes when one
tries to exit it.  I also fixed some memory issues.  I have SDL2_ttf
(SDL_ttf) support working (as an alternative to Cairo).  Added ability
to use nanosvg in place of rsvg if desired.  I made some modifications
for internationalization.  I'm using unistring library instead of the
old Unicode line-breaking code borrowed from gettext that was added to
t4k_common.  t4k_common build works with newer or older versions of
libpng.

Would anyone like to help test what I've modified so far?  My patches aren't in
the official tuxmath git repos, so let me know if you want to test and
I'll get you
a copy of the patches.
