   * zr36120.c: made sure illegal clipping zones are not discarded
		but corrected so they will have an effect. This is
		especially usefull when the overlay is on a screen
		border.

   * zr36120.c: Whoops, setting bpl in the SETFBUFFER ioctl would
		set the overinfo.bpl variable, but the GETFBUFFER 
		ioctl would return a totaly different variable!
		(The offending variable is removed)

   * zr36120.h: made debugging information default to off. Also
		turned off PCI write checking in zror, zrand etc.
		calls. This improves the setup speed a lot.

   * zr36120.c: corrected small typo in stride determination for
		non-interlaced heights. Reversed arguments.

   * zr36120.c: display warning when stride gets negative. I know
		this shouldn't happen, but just in case...

Started a changelog to keep track what I'm doing.
