* Quota Display
*
* Modify the following few elements to change the display of the image.
* Modifiable attributes are:
* bool border :: Defines whether you want to show a border around it or not.
* bool unknown :: Leave default; Defines whether quota is "unknown"
*
* int height :: Defines height of the image
* int width :: Defines width of the image
* int font :: Changes the font size & font used in the GD library.
* Available values are from 1 to 5.
* int padding :: Changes the offset (in pixels) from the top of the image to
* where the top of the text will be aligned. User greater than
* 0 to ensure text is off the border.
* array limit :: Holds the integer values of in an associative array as to what
* defines the upper and lower levels for quota display.
* High - Quota is nearing capacity.
* Mid - Quota is around the middle
* Low - Currently not used.
* array color :: An associative array of strings of comma separated values (R,G,B)
* for use in color creation. Define the RGB values you'd like to
* use. A list of colors (and their RGB values) can be found here:
* http://www.december.com/html/spec/colorcodes.html
