Christoph Oelckers	09f54b0940	- cleaned up the clip plane management for portals. ...

It wasn't working anyway.	2016-04-27 00:41:00 +02:00

Christoph Oelckers	d868f60f6c	- since the clip planes for plane mirrors did not work anymore I reimplemented them using shader based logic. It still needs to be seen if this affects performance on older hardware.	2014-07-13 12:14:12 +02:00
