Watermarks for TXTextControl

Printing with watermarks (e.g. draft) - a very useful feature, especially when the generated document has to go through an approval process.

TXTextControl doesn't support this itself - but by sub-classing the PrintControllerWithStatusDialog and overriding the OnEndPage this can be rectified - the trick is to use an alpha value in the brush to make it semi-transparent.

For full details take a look on the TXTextControl support site - there's a thread there with some example code we wrote in it.
