Description

pinq_int_facs_plus returns the following values:

•Number and list of available interior styles

•Number and list of available hatch styles

•Number and list of available shading methods

•Number of predefined interior indexes

•Number and list of available lighting methods

The value of the number of available hatch styles has the following interpretations:

Value       Result
------------------------------------------------------------------------
Positive    The list of available hatch styles contains all registered
            hatch styles.
Negative    Two conditions apply:
            - Digital PHIGS derives the implementation-specific hatch
              styles directly from the value and the hatch style aspect.
            - The list of available hatch styles contains the registered
              hatch styles supported, the number of which is the
              absolute value of the number of available hatch styles.
