Subject: [PATCH]   * Allow pipi --blur to specify both the X and Y Gaussian
 sizes. Now we can     create some nice, tileable brushed metal textures:     
    pipi pipi:random15x15 --geometry 512x512 --wrap --blur 40 \             
 pipi:random512x512 --wrap --blur 10x0 --autocontrast --wrap \             
 --blur 20x0 --multiply -o image.png
