New Revision: 7482

Modified:
   trunk/gs/doc/pscet_status.txt
Log:
Fix : A wrong 'frac' color comparison caused an incorrect 12 and 16 bpc image rendering.

DETAILS :

Debugged with CET 12-07C.PS page 15 and disassembling gxi12bit.obj .

The old code wrongly computed how many 'long' values are needed to store 4 'frac' values. 
When sizeof(long)==4 and sizeof(short)==2 it gives 1.
However the right answer is 2.
Due to that the old code thinks that 'frac' colors are equal 
when they differ in 3d or 4th component.

EXPECTED DIFFERENCES :

None.
