@M@bInclude Preview

Include Preview allows you to view some of the textures and geometries defined
in the *.inc files that are distributed with POV-Ray.  For most of the
selections, the type is automatically set for you.  For example, if you choose
to preview "Color", the type is set to "Pigment".  However, for the Metal and
Gold previews, you must choose the appropriate type (either "Pigment" or 
"Texture").  If you do not set the correct type, POV-Ray will generate an error.

The code used to parse the *.inc files is not sophisticated.  Some entries 
in the selection list are erroneous, and will not produce an image.   The 
filter used to parse the *.inc files requires the utilities grep, sed, and
cut. 

The text input boxes allow you to set the (x, y, z) positions of the camera,
camera viewpoint, and light source.
 
Show Axes will draw a set of axes for reference (left-handed coordinate system, 
with red denoting the x-axis, green the y-axis, and blue for the z-axis).

The size of the rendered preview is given by the current image size that is
set on the main widget.
