/**
* 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?
* 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
*
* @return void
*
* @param mixed $used The amount used, or ?? if unknown.
* @param mixed $total The total available, or ?? if unknown.
* @param int $width Width of the image.
* @param int $height Height of the image.
*
* @see rcube_imap::get_quota()
* @see iil_C_GetQuota()
*
* @todo Make colors a config option.
