The IMAGE_LIGHT block items provide interactive lights
(1-4) control.

The menu is loaded with the file
"MAIN_CMDS:load_image_light.com".  

It uses two macros.  "MAIN_CMDS:image_light_mode.cmds"
switches among modes. The radio buttons indicate which mode
will be applied.  

"MAIN_CMDS:image_light_funct.cmds" invokes the chosen
function (by mode status variable) on the specified light
(LIGHT_1 to 4).  Clicking this buttons can change
the light status and definitions.

3 TURN_ON

Turns the light on mode.

3 TURN_OFF

Turns the light off mode.

3 DIALS

Turns the dial light manipulation mode.  The dials can
manipulate a light COLOR, DIRECTION angles, DISTANCE and
distance ATTENUATION parameters.

3 AMBIENT

Turns the AMBIENT light mode.  An ambient light comes from
all directions.  It has only COLOR parameters.

Turns the DIRECTION light mode.  An directional light comes from
a defined direction.  It has COLOR and DIRECTIONAL parameters.

3 POSITION

Turns the POSITIONAL light mode.  A positional light comes from
a defined position. Light is spreaded in all directions.
The light has COLOR, DIRECTION and DISTANCE and distance attenuation
parameters.  (Direction and distance define a position.)

light which shines in a cone.  It has therefore two
attenuation paramaters, a distance and angle.
