We have been discussing about removing libpng.pc, libpng.so and
unversioned headers from the libpng 1.5.x package allowing it to install
parallel with libpng 1.4.x.

i dont see any real advantages with SLOT-ed installs of libpng beyond ABI
(i.e. what we're doing today with libpng-1.2.x and libpng-1.4.x). there are
however plenty of downsides. patching packages in the tree is a huge hassle,
you add hassle to end users who d/l random packages and try to build things
themselves, and you make Gentoo non-standard wrt every other distro out there.
best we follow what everyone else is already doing, and what upstream packages
will have to ultimately do anyways -- fix their code to work with libpng-1.5
when the API has been forcibly broken.
Or you can mask libpng-1.5 since most users aren't interested in having
the latest version of something they won't be using directly. Wait
until packages have been fixed upstream. Then 8 months or a year later,
unmask it.
