+- Update to version 1.11:
+  * A GeoJSON backend was added.
+  * Support for bitfields in the BMP format was added.
+  * A minor change was made to the behavior of the alphamax
+    parameter; a value of 0 now gives a true polygon. 
+- Build shared libpotrace.

+Potrace is a utility for tracing a bitmap, which means, transforming a
+bitmap into a smooth, scalable image.  The input is a bitmap (PBM, PGM,
+PPM, or BMP), and the default output is one of several vector file
+formats.  A typical use is to create EPS files from scanned data, such
+as company or university logos, handwritten notes, etc. The resulting
