So far, I have installed on my system:
libpng-dev (1.6.28-1)
libpng++-dev (0.2.9-1)
libsdl1.2-dev (1.2.15+dsfg1-4)
libsdl2-2.0-0 (2.0.5+dfsg1-2ubuntu3)

I do not see any direct conflict on the listed dependencies of
libsdl1.2-dev to libpng.

Interestingly, there is a libsdl2-dev which can be installed in parallel
to libsdl1.2-dev

I also have the libpng12-0 (as runtime), along with libpng16-16.

But I remember that upgrade of release usually try to remove a lot of
"unnecessary" packages, aka packages it does not see the need for... and
it is not good at it when you have locally compiled applications.
