layoutOrientation
long layoutOrientation()
A property describing the receiver's layout orientation. This property defines the default value for the range of string laid out in the receiver in absence of explicit NSVerticalGlyphFormAttributeName attribute. For example, when NSTextLayoutOrientationVertical, the default value for NSVerticalGlyphFormAttributeName is 1. When rendering into the receiver, the Text System assumes the coordinate system is appropriately rotated.
