use pdfminer's analysis and iterate.
Make iteration predicate and return more generic.

James R. Barlow c1e18bb825 optimize: Exclude soft masks (SMasks) from optimization 
Soft masks are only allowed to be of colorspace DeviceGray so we
shouldn't use pngquant on them. For now, avoid this exceptional
case by excluded soft masks from optimization.
