I finally got bored by the primitive navigation in Fract so I added re-centering by clicking. Fortunately when I asked the people on #lisp if it was good enough they told me that it was too slow. If they hadn't I could have left it with the tiny little 100x100 image. Since Xach had just finished his GIF writer he proposed it as an alternative to CL-SDL which is quite fast but only saves to BMPs.
Skippy, the GIF writer, only does point operations but thats exactly what I needed (and makes coding the Poly-pen back-end a lot less work). Poly-pen proved it's usefulness since I was able to switch the back-end in Fract without any trouble for the greater good of the greater number. Xach's back-end is in pure Lisp, I think crossing the UFFI takes a lot of CPU cycles since I was able to double the image size while reducing the rendering time. One of these days I should code some benchmark suite for all the back-ends in Poly-pen.
So you can now enjoy Poly-pen 0.3.1 featuring improved histograms and a new ultra-fast back-end for GIFs and Fract 0.5: faster with bigger images and improved navigation!
Enjoy!
