I second this idea. Very good.
I've started to think of doing quick rewrite of Shapelib to a
single-header file with a shapefile class providing iterator-based
interface, so it's just easy to read test files.
I eventually deferred this idea to limit distractions for now :-)

libgd is good I think, it's just a few files we could keep in our repo.
BTW, if you are interested in using libgd under Windows (as a simple
replacement to GDI), a wile ago I added utility function
gdImageTrueColorAttachBuffer to libgd for that purpose, here is example:

It is a little strange, indeed.
