I'm pleased to announce that GraphicsBuilder 0.4.5 has been released (as promised). It includes some bugfixes and new features as filters (outlined here and here). The current filter count is 60 (a lot of work to create bindable/animatable wrappers) Here is the current list

["average", "blur", "boxBlur", "brushedMetal", "caustics", "cellular", "check", "chromaKey", "chrome", "circleDistort", "contour", "contrast", "convolve", "crystallize", "curl", "despeckle", "detectEdges", "diffuse", "diffusion", "dilate", "displace", "dissolve", "dither", "dropShadow", "emboss", "embossEdges", "equalize", "erode", "erodeAlpha", "exposure", "fade", "fbm", "feedback", "fieldWarp", "fill", "flare", "flip", "flush3D", "fourColorFill", "fractalBrownianMotion", "gain", "gamma", "gaussianBlur", "glint", "glow", "grayOut", "invert", "kaleidoscope", "lights", "marble", "material", "mirror", "mosaic", "pointillize", "ripple", "shapeBurst", "smear", "water", "weave", "wood"]

The svg2Groovy script is also included (the layout needs some work), bear in mind that it only transforms a subset of SVG for the time being.
Feedback is always appreciated.

Keep on Groovying!
