[gs-cvs] Improving log message for rev 8386 - trunk/gs/src

[Leonardo]

The log message has been edited as this :

[beg quote]
Fix (transparency) : Wrong background color of a soft mask group.

DETAILS :

Bug 689531 "Regression: PDF file has undesired extra gray object.".

The old code used the 0th component of the background color
instead its gray equivalent.  The bug was introduced when
working on bug 687176.

EXPECTED DIFFERENCES :

None (comparefiles don't include a test for it).
