Re: [png-mng-misc] aPNG-0.4

[Glenn Randers-P. <gl...@co...>]

I've posted an additional suggestion on the aPNG spec bug at bugzilla.mozilla.org.  That is to make the aPNG chunks copy-safe,
by including the CRC's from IHDR and PLTE in the aCTL chunk.  (I
don't think and editor changing IDAT without changing either IHDR
or PLTE would invalidate the aPNG chunks).  The copy-unsafe chunks
proposed in APNG-0.4 are just too likely to get inadvertently discarded.
