I was trying to get advanced gradients working, with a use syntax like...
gradient = new AdvancedGradientFill(0, -75, 0, 75);
I actually got this working, however, because of the way ShapeRenderer draws, it doesn't work, even with the AdvancedGradientFill class implementing ShapeFill because it will draw a shape with the least amount of verticies possible.
Is there a way we could have this work by splitting up the shape being drawn using the new SVG Triangulator stuff, and then using the triangluated polygon to draw the shape?
Sure, it would use a lot more polygons, but it would make this feature work well, and with the new display lists function added to slick, it might not be a big performance hit.
