I was experimenting with the latest version of fontforge, which can use
giflib 5.x. For the time being it can be left out.
An updated patch is attached.

+company or university logos, handwritten notes, etc. The resulting image is
+not \"jaggy\" like a bitmap, but smooth. It can then be rendered at any
