patch to fix graphite_layout.cxx compile failure with libc++ version 3.8.0
As documented here: <https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=209588>,
vcl/source/glyphs/graphite_layout.cxx fails to compile with libc++ version
3.8.0 with this error:
/wrkdirs/usr/ports/editors/openoffice-4/work/aoo-4.1.2/main/vcl/source/glyphs/graphite_layout.cxx:297:21:
error: call to 'round' is ambiguous
long nXOffset = round(fMinX * fScaling);
^~~~~
The problem is that graphite_layout.cxx defines this inline function:
inline long round(const float n) {
return long(n + (n < 0 ? -0.5 : 0.5));
}
which matches the overloaded float round(float [...]) library function other
than the return type.
Fix this problem by renaming the local function to round2long() to make it
unambiguous and better describe its functionality. Adjust all of its callers
to match.
