.SS Purpose
\s-2SET INTERIOR COLOUR\s+2 creates a structure element
to set the interior 
colour attribute.
.LP
When the current interior colour Aspect Source Flag (\s-2ASF\s+2) is set to
\s-2INDIVIDUAL\s+2,
the current value of this attribute
defines the interior colour to be applied to the following output primitives:

.SS Execution
Depending on the edit mode, a \s-2SET INTERIOR COLOUR\s+2 element 
is 
inserted into the open structure after the element pointer or replaces
the element pointed at by the element pointer. The element pointer
is then updated to point to this \s-2SET INTERIOR COLOUR\s+2 element.
.LP
When the current interior colour \s-2ASF\s+2 is set to
\s-2INDIVIDUAL\s+2, filled-area output primitives
that follow in the structure network are filled using
the current interior colour.
.LP
When the current interior colour \s-2ASF\s+2 is set to \s-2BUNDLED\s+2,
the interior colour is taken from the
workstation extended representation indicated by the current interior index.
In this case, the interior colour
set with \s-2SET INTERIOR COLOUR\s+2 has no effect.
.LP
The standard \s-2PHIGS\s+2 function \s-2SET INTERIOR COLOUR INDEX\s+2
is equivalent to calling to \s-2SET INTERIOR COLOUR\s+2 with type
\s-2INDIRECT\s+2.
