Fix coding convention R.RN7 (Avoid the raw C types 'long', 'unsigned long', 'long double', 'bool', 'long long' and 'unsigned long long'.)

the proxy for string to support the Data member function and to add
a direct operator const char*().

fixing the detection that a TTreeFormula is a string or not.

Move to using kIsCharacter only as an accelerator to TTreeFormula::IsString
and always use this function to detect whether the formula is a string or not.
Fix (in TTreeFormula::Init) several cases of string detection and remove from
TFormula any settings (they were wrong anyway, they should have been ResetBit
rather than SetBit) of kIsCharacter.

(which means check 10^6 pixels every time if shadow path is not specified) set shadows in
a context - so Quartz knows exactly, what produces a shadow.
2. Remove "paint shadow" functions from pad painter.
3. Cleanup.

1. When object selected in a pad, do not highlight it, only draw a shadow (like it's above the other pad's primitives).
2. Use quartz smooth shadow.
3. During device rotation, switch the shadow off (calculation is very expensive for arbitary path) - thanks to Olivier for idea.

where the incremental merging fails if the TTree are stored in sub-directories.

This is fixed by passing the incremental flag down the RecursiveMerge chain
and making sure the TDirectory of the output file are not deleted until the
end (since flushing them is also delayed until the end).

Also remove redundant 'if is-a-collection' test.
