Flow Area Rect logical
Following on bug 1062963, we need to make the nsFlowAreaRect used by all the AvailableSpace methods in nsBlockReflowState.cpp contain a LogicalRect instead of an nsRect.
Presumably all of the rects in a single float manager will have the same writing mode?
Yes, at least at any given moment.

Addressed review comments and added some changes in nsLineLayout.cpp which I had as a separate patch originally and forgot to include before. I made FloatMarginISize more readable slightly differently from how you suggested, but I hope you like this way too.

Good catch! Me: "This is such a trivial change, no need to make sure that it still builds". I'll make sure to do another try run of the patch queue from bug 1062963 and here before checking in.
Backed out both this and bug 1062963 in https://hg.mozilla.org/integration/mozilla-inbound/rev/2c490d1c97b0 because I didn't know which caused the failures in 427129-table-caption.html (permaorange in b2g reftest-6, intermittent in Android 2.3 reftest-5).
