wineps: clipping bug; clipping performance

[Wolfgang Walter]

Hello,

as I wrote clipping in wineps.drv has a bug. Wine does only consider the 
clipping region and not the meta region. It should combine them. This is a 
bug which hurts us with a real windows application.

I sent a patch which which corrects this.

My patch also addressed a general performance problem with all postscript 
printers from Kyocera concerning non trivial clipping regions. Even if you 
use ghostscripts pxlmono/pxlcolor driver the generated PCL XL code may lead 
to errors on our Kyocera and HP printers because the clipping path gets to 
expensive.

I have not received any comment yet.

Regards,
