Summary: width="0" no longer makes image invisible

New Features:

Bugs Fixed: LPP-7936

Technical Reviewer: ptw
QA Reviewer: max
Doc Reviewer: (pending)

Documentation:

Release Notes:

Details:

+ swf9, make sure to set scaleX,scaleY to zero if there is a width
specified, even if it's zero. The "if" clause was getting faked out
because "if (lzwidth && ...)" evals to false if lzwidth == 0.

+ swf8, allow the sprite's movieclip _xscale to go to zero, so a
resource can become invisible.

But needed to add a special case to measure resource width and height
when _xscale == 0, in updateResourceSize(), due to calculating it from
the sprite movieclip's _width and _xscale


Tests:

+ test case from bug report, resource should be invisible (swf8, swf9)

+ test case from LPP-6656 still works; stretched resource in  
resizelayout visible and proper width (swf8, swf9)
