Small question: line-layout and markers

[Andreas L Delmelle]

Hi all
Just a check to see if anyone knows off-hand how the availIPD.opt  
that is passed into Paragraph.startParagraph() in  
LineLM.collectInlineKnuthElements() would influence marker-retrieval.

Reason I'm asking is that I noticed the TODO on  
collectInlineKnuthElements() to remove the availIPD parameter from  
its signature. So, I decided to try removing it and using the  
LayoutContext's stack limit instead. All tests pass, apart from  
markers_4 and markers_5b...


Cheers

Andreas
