for the record, you can create a "worldfile" for a PNG the same
as for a plain TIFF image, and GDAL will pick it up. It needs to
be named the same as the image but with a .pgw extension.
I'm not sure if anything other than GDAL-based things would
respect that though, or if this trick helps for Sudeep's
question or not.
(GDAL's virtual-raster format is another wonderful cpu-saving
device worth mentioning btw)
