Some fixups to row margins

Browse Source 
In breakRow set left and right margin properly for RTL paragraphs.
Remove corresponding code from ComputeRowMetrics.

In row painter, check the use of left and right margin depending on
context. The problem in the original text is that the various
leftMargin() methods actually represent right margin for RTL
paragraphs. This should be fixed eventually.
