The <dotj:watermark> tag can be used to display a watermark image for the background of the page. Since it is a watermark,
it is fixed and will not move when the page is scrolled.
Newer web browsers support this feature, but older ones will ignore the image.
The tag can be placed anywhere in the JSP page since it effectively does not add any content to the page. If more than one watermark
tags are placed in a JSP, then the first one is used and the others will be ignored.
The location attribute can be used to control where on the page the watermark will display. Options are:
Top left
Top center
Top right
Center left
Center center (the default)
Center right
Bottom left
Bottom center
Bottom right
