/*

*
|
* Add w:document/w:background; note that this is only visible in Windows Explorer file preview, or
|
* Word's "Web layout" and "Full screen reading" document views (ie not Print Layout, Outline,
|
* or Draft). Checking Word options > Display > Printing options > Print background colors and images
|
* makes no difference to what you see in Print Layout, but it does change what you see in Print Preview.
|
*
|
* This is different to a watermark, which is set via the headers (see WatermarkPicture sample for that),
|
* which is probably what you want.
|
*
|
* From [MS-OI29500]:
|
*
|
* a. The standard states that any element from the VML namespace or the drawingML namespace
|
* is allowed as a child of the background element.
|
*
|
* Word renders any drawingML specified as a background at the beginning of the document and not as a background.
