For now, only COL and ROW are supported.  More on the way.  Note that
we can't support all the information types that we do for internal
references.

 * on OSX 10.5 PPC, ld crashes with a bus error, presumably because
   of the empty ar[] string array.
 * the "size = 0" default case looks wrong, replaced by *size=0

Some places in the code assumed that if the stack is empty a null pointer is
returned by top() (or old Pop()), this doesn't work anymore with ::std::stack
that instead has undefined behavior in that case, so check !stack.empty()
first before accessing top.
(cherry picked from commit ac40f7d6)

gsoc input bar now (should) snuggly wrap the text when collapsed, if multilines exist then scrolling with the keys should be clean and no spill from upper or lower lines visible. Removed some strange ( pseudo padding ) apparently for taking into account the window border and reorganized the resize logic so the padding is added ( and commented why ) in just one place.

Another unfortunate logic change introduced via DECLARE_LIST removal.
Reverting the logic to the original one.

I'm pretty sure I'll love to use it in writerfilter instead of the normal
API whenever I get the chance.
