Title: Upgrade to libpng15

After upgrading from libpng14 to libpng15 it's important that you rebuild
cairo and gdk-pixbuf soon as possible if they are installed.

Then you can proceed with rebuilding rest of the software against the new
library:

# revdep-rebuild --library libpng14.so.14

In case of failure, try skipping the failing package and rebuilding it 
later in the process.

If you find packages not building with message "ld: cannot find -lpng14",
they are likely caused by broken libtool archives (.la) in your system.

You can identify those files with following one-liner:

# find /usr/ -name '*.la' -exec grep png14 {} +
