[Debian-astro-maintainers] Bug#810209: yt: Please update dependency on libpng-dev

Followup-For: Bug #810209

Looking into it (with my limited pyhton knowledge), I think it is using matplot lib for its png need:

File yt/utilities/png_writer.py:

(...)
import matplotlib._png as _png
(...)
if MPL_VERSION < MPL_API_2_VERSION:
    def call_png_write_png(buffer, width, height, filename, dpi):
        _png.write_png(buffer, width, height, filename, dpi)
else:
    def call_png_write_png(buffer, width, height, filename, dpi):
        _png.write_png(buffer, filename, dpi)
