loading and saving pngs work.
While here, fix a small string buffer that was truncating some libpng
messages, and avoid a linker warning by using getcwd instead of getwd
on BSDs.
No version bump as it hasn't been buildable since the previous bump.
pull in the Jumbo patches from http://www.sonic.net/~roelofs/greg_xv.html.
As far as I can see this covers all our existing patches for added
functionality, although I cannot claim that I have tested each and
every one of them in the new version.
These patches disable a number of image formats that I think are less
common, which have potential heap overflows in the code due to in-
sufficient validation of image dimensions.
The version of the Jumbo patch used here is the 20050501 version.
Package revision bumped to nb10.
