[PATCH] Auto-detect page directionality for floating TOC

[Itamar Oren]

The problem: when including a floating TOC in right-to-left pages, the TOC floats on the right, which is "not right".

The fix: Make the floating aware of page directionality (complex, depends on ​ticket:4431) and set floating position accordingly.

Workaround until then (attached patch): Simple heuristic - if the page begins with:

{{{
#!div dir=rtl
...
}}}

then assume it is right-to-left.

Also add "float=<dir>" argument that allows overriding auto-detection and setting the floating direction manually.

Update: No need for this!

See DirClassMacro.

TOC used within [[RTL]] block will float on the left.
