       IMPORTANT: Due to the static usage of this class this
       method sets the tint color statically. So it is highly
       recommended to call the clearColorTint method when you
       have finished drawing. 
     
       Sets the color to use when drawing the SVG. This replaces
       all parts of the drawable which are not completely
       transparent with this color.
