PIL plugins for obscure image formats

I've written two read-only PIL plugins for obscure image formats over the past few years. I offered them up for PIL inclusion on image-sig, but received no response whatsoever.

Anyway, here they are:

icns:

Decoder for the Mac OS X 'icns' resource format

SoftimageImage:

Decoder for lossless Softimage PICT (.pic) files
