Watermark:

--------------------------------------------------------------------------
   Add a watermark to a figure. 
   This function creates two axes, one for the image and one for the text. 
   Calling it BEFORE plotting can cause unexpected results. It will reset 
   the current axes after adding the watermark. The default position is
   the lower left corner, (2,2).
   Leaving out the color input will cause the logo to use the color of the
   figure for the background.
