As a general principle, it makes no sense for pdftex to provide image
manipulation capabilities.  Such capabilities are useful to a much wider 
audience than the users of pdftex, so there are lots of tools to do
image resampling and format conversions.  All that pdftex should do is
support inclusion of pdf.  The limited support for including png images
is a convenience, but if you are being careful you would want to make
pdf images.
