Bug#303700: Please build-depend on libpng12-dev

[Josselin Mouette <joss@debian.org>]

Package: meshio
Severity: wishlist

Post-sarge, the libpng3-dev package will be removed. Currently, this
package has a versioned build-dependency on libpng3-dev. When
libpng3-dev will be removed, it will still be provided by libpng12-dev,
but that won't work for versioned build-dependencies, and the package
will fail to build.

Thus, please make the package build-depend on libpng12-dev instead.

Regards,
