AcGiViewportTraits

acgiviewport.h

Viewports, on both Model and Layout tabs, now recieve a call to their AcDbViewport::setAttributes() method before AcDbViewport::worldDraw(), similar to entities. This gives viewports the opportunity to pass per-viewport properties to the display and rendering systems.  

A concrete instance of this interface class is passed to both AcDbViewport::setAttributes() and AcDbViewportTableRecord::setAttributes(). Set calls on this interface should then be made by the viewport object. 

This class derives from AcGiDrawableTraits.
