 /**
  * Set the axis padding for a specified position.
  * 
  * The axis padding is padding "inside" the plotarea (i.e. to put some space
  * between the axis line and the actual plot).
  * 
  * This can be specified in a number of ways:
  * 
  * 1) Specify an associated array with 'left', 'top', 'right' and 'bottom'
  * indices with values for the paddings. Leave out 2nd parameter.
  * 
  * 2) Specify an overall padding as the first parameter
  * 
  * 3) Specify the padding and position with position values as mentioned
  * above
  * 
  * Normally you'd only consider applying axis padding to a category x-axis.
  * 
  * @param mixed $value The value/padding
  * @param mixed $position The "position" of the padding
