[gl2ps] Problem with BSP printing (reason found)

[Shahzad MUZAFFAR]

Hello,
  I have already mentioned (in one of my previous email) about the 
problem with BSP printing not working properly in 1.2.3 and up releases 
(i.e. printing in reverse order). I think I have found the reason. The 
problem is in the gl2psRescaleAndOffset() method. The problem occurs 
when the scaleZ becomes > 100000. Because at scaleZ > 100000 the 
z-coordinates of all primitive become > 100000 which is above the EYE 
set in the gl2psPrintPrimitives() method. Thats why we see eps/pdf files 
printed in reverse order.
 
I have added this line in gl2psRescaleAndOffset() method

if (scaleZ > 100000.F) scaleZ=100000;

to force the Z scaling. And now printing works properly. Cheers,
