I'm really no expert on this, but as nobody else told you this, I will: Gecko 1.9 will use cairo for rendering and cairo supports several different surface types (including PDF and PNG as output) you could in principle render directly to one of those surfaces. I know that at least on Linux and Windows the PDF surface can be used to print to file. If you search for "gfxPDF" on http://mxr.mozilla.org/seamonkey/ this might give you a hints. I don't see why this shouldn't be possible with a PNG surface. Of course then you have to create a build that actually compiles in the the code to create a PNG surface. > Assuming this is possible (lets be honest, it's probably not exactly > what Gecko was designed for), is this something that is likely to be > do-able in a reasonably cross-platform sense?

As those surfaces are all platform independent in cairo anything that you invent should work for all platforms.
