[Scummvm-devel] png

[Filippos Karapetis]

The only missing thing in our custom PNG code (based on LodePNG) was
support for interlaced PNGs, which are rarely used in games (apart from
some WME indie games). This is what that pull request refers to. The rest
of the code does function...

If you do wish to drop the custop PNG decoder, shouldn't we do the same
with the JPEG decoder and use libjpeg? IIRC, that one also had missing
features.

Filippos
