           Summary: Support for 8bit transparent animations via MNG.
           Product: WebKit
           Version: 420+ (nightly)
          Platform: All
               URL: http://www.libpng.org/pub/mng/
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: Enhancement
          Priority: P4
         Component: Images
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: john at discrevolt.com

At the moment, raster animations are only possible with animated GIFs which
support just 1 bit transparency. Other possibilities just aren't sufficient,
both Flash and SVG are vector-based and not always appropriate.

Note: I personally do not care much about the patent issues that seemed
relevant to the GIF debate of years gone by, and besides, I believe those
patents have all expired recently.

An alternative might be the APNG format, but I do not consider myself qualified
to weigh the advantages and disadvantages of MNG vs. APNG.
