-Update to 1.9
+the XFig and EPS backends were improved, and a fixed pagesize PDF backend was added;
+ support for BMP version 4 and version 5 files, as well as top-down BMP files, was added;
+ you'll see minor speed improvements to Potrace and major speed improvements to mkbitmap;
+ a Gaussian blur option was added to mkbitmap;
+ a change in the build sustem: libtool is now used to build and optionally install the Potrace library;
+ an optional simplified progress bar was added for dumb terminals;
+ this release also contains some portability improvements, cross-compilation improvements, and minor bug fixes.
- run spec cleaner on the spec file and remove redundant changes from spec
- drop xfig-patch as it is upstream now
