* KoWmfPaint inherits the abstract class KoWmfRead
* and redirects WMF actions onto a TQPaintDevice.
* Uses relative or absolute coordinate.
* how to use:
* <pre>
* TQPixmap pix( 100, 100 );
* KoWmfPaint wmf;
* if ( wmf.load( "/home/test.wmf" ) ) {
* wmf.play( pix );
* }
* paint.drawPixmap( 0, 0, pix );
* </pre>

* play WMF file on a TQPaintDevice. Return true on success.
* Use absolute or relative coordinate :
* absolute coord. reset the world transfomation Matrix (by default)
* relative coord. use the existing world transfomation Matrix
