Noel Grandin 794d5ac4ac vcl: use enum for complex text layout constants 
Since these constants are bitfield flags, we define some methods to make
working with them reasonably type safe.

Move the definitions to outdevstate.hxx, since we need the values there,
and that appears to be the "root most" header file.

Also dump TEXT_LAYOUT_BIDI_LTR constant, since it means the same thing
as TEXT_LAYOUT_DEFAULT (ie. 0), and leaving it in causes people to write
weird code thinking that it's a real flag.

/* HACK: There is something wrong with Writer's bullet rendering, causing lines
with bullets to be higher than they should be. I think this is because
Writer uses font's external leading incorrect, as the vertical distance
added to every line instead of only a distance between multiple lines,
which means a single bullet has external leading added even though it
shouldn't, but frankly this is just an educated guess rather than understanding
Writer's layout (heh).
Symbol font in some documents is 'StarSymbol; Arial Unicode MS', and Windows
machines often do not have StarSymbol, falling back to Arial Unicode MS, which
has unusually high external leading. So just reset external leading for fonts
which are used to bullets, as those should not be used on multiple lines anyway,
so in correct rendering external leading should be irrelevant anyway.
Interestingly enough, bSymbol is false for 'StarSymbol; Arial Unicode MS', so
also check explicitly.
