Pattern Fills 

A colleague of mine made the following request on your forum for the ability of pattern fills for bar charts:

I was able to implement the functionality and thought that you might want to take a look at it.  I tried to follow the method that you used for gradient fills.  The syntax for usage is: 

{
  patternImage: <path to pattern image>,
  patternImageDimensions: [width, height]
}

Unfortunately SVG-enabled browsers don't use the default dimensions of the pattern image, so it is necessary to define the image dimensions.  I would recommend using a pattern image of a width of 16 pixels and 12 pixels since that seems to be the size of a legend item.
