Requested color space awareness for png files

[boarder's paradise]

kindly suggesting:

color space awareness for png files
(so that png files are displayed in the right colors, to put it very simply)

this requires in turn:
support (read/write) of the following png chunks:

1) (most importantly iCCP (Embedded ICC profile)
2) cHRM (Primary chromaticities)
3) gAMA (Image gamma)
4) sRGB (Standard RGB color space)


... as part of an effort to make IV fully color-managed.
cheers.

with hdd space growing bigger and cheaper and - as a consequence - lossless formats (including lossless image formats such as png) gaining importance, this wish is now more relevant than ever
