Now that I have a better handle on how Alpha values work, I have gotten the Diagram Designer to use and pass them along to the PNG file. I have added a new parameter to drawdiagram.php called bgcolor, which is for the background color used when shrinking an SVG image to a particular size. Its default is FFFFFF00, which is a fully transparent white. When the Alpha value is given in bgcolor, it will just use the generated Alpha values for each pixel. When the Alpha value is not given, it will just color the outer area with a transparent color. The left image uses FFFFFF00 for the background color, and the second uses 666666 for the background color.
