-_phead(_param3)
-Specifies a pointer to the value or values that parameter _param2
-of light source _param1 will be set to.
-.SH DESCRIPTION
-_cmnd sets the values of individual light source parameters.
-_param1 names the light and is a symbolic name of the form _const(LIGHT)$i$,
-where 0 \(<= i < _const(MAX_LIGHTS).
-_param2 specifies one of ten light source parameters,
-again by symbolic name.
-_param3 is either a single value or a pointer to an array that contains
-the new values.
-.P
-To enable and disable lighting calculation, call _cmnd(Enable)
-and _cmnd(Disable) with argument _const(LIGHTING). Lighting is
-initially disabled.
-When it is enabled,
-light sources that are enabled contribute to the lighting calculation.
-Light source $i$ is enabled and disabled using _cmnd(Enable) and
-_cmnd(Disable) with argument _const(LIGHT)$i$. 
-.P
-The ten light parameters are as follows:
-.TP 20
-_const(AMBIENT)
-_param3 contains four integer or floating-point values that specify
-the ambient RGBA intensity of the light.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial ambient light intensity is (0, 0, 0, 1).
-.TP
-_const(DIFFUSE)
-_param3 contains four integer or floating-point values that specify
-the diffuse RGBA intensity of the light.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial value
-for _const(LIGHT0) is (1, 1, 1, 1); for other lights, the
-initial value is (0, 0, 0, 0). 
-.TP
-_const(SPECULAR)
-_param3 contains four integer or floating-point values that specify
-the specular RGBA intensity of the light.
-Integer values are mapped linearly such that the most positive representable
-value maps to 1.0,
-and the most negative representable value maps to \-1.0.
-Floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-The initial value
-for _const(LIGHT0) is (1, 1, 1, 1); for other lights, the
-initial value is (0, 0, 0, 0). 
-.TP
-_const(POSITION)
-_param3 contains four integer or floating-point values that specify
-the position of the light in homogeneous object coordinates.
-Both integer and floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-.IP
-The position is transformed by the modelview matrix when
-_cmnd is called (just as if it were a point),
-and it is stored in eye coordinates.
-If the $w$ component of the position is 0,
-the light is treated as a directional source.
-Diffuse and specular lighting calculations take the light's direction,
-but not its actual position,
-into account,
-and attenuation is disabled.
-Otherwise,
-diffuse and specular lighting calculations are based on the actual location
-of the light in eye coordinates,
-and attenuation is enabled.
-The initial position is (0, 0, 1, 0);
-thus, the initial light source is directional,
-parallel to, and in the direction of the $-z$ axis.
-.TP
-_const(SPOT_DIRECTION)
-_param3 contains three integer or floating-point values that specify
-the direction of the light in homogeneous object coordinates.
-Both integer and floating-point values are mapped directly.
-Neither integer nor floating-point values are clamped.
-.IP
-The spot direction is transformed by the inverse of the modelview matrix when
-_cmnd is called (just as if it were a normal),
-and it is stored in eye coordinates.
-It is significant only when _const(SPOT_CUTOFF) is not 180,
-which it is initially.
-The initial direction is (0, 0, \-1).
-.TP
-_const(SPOT_EXPONENT)
-_param3 is a single integer or floating-point value that specifies
-the intensity distribution of the light.
-Integer and floating-point values are mapped directly.
-Only values in the range [0,128] are accepted.
-.IP
-Effective light intensity is attenuated by the cosine of the angle between
-the direction of the light and the direction from the light to the vertex
-being lighted,
-raised to the power of the spot exponent.
-Thus, higher spot exponents result in a more focused light source,
-regardless of the spot cutoff angle (see _const(SPOT_CUTOFF), next paragraph).
-The initial spot exponent is 0,
-resulting in uniform light distribution.
-.TP
-_const(SPOT_CUTOFF)
-_param3 is a single integer or floating-point value that specifies
-the maximum spread angle of a light source.
-Integer and floating-point values are mapped directly.
-Only values in the range [0,90] and the special value 180
-are accepted.
-If the angle between the direction of the light and the direction from the
-light to the vertex being lighted is greater than the spot cutoff angle,
-the light is completely masked.
-.BP
-Otherwise, its intensity is controlled by the spot exponent and the
-attenuation factors.
-The initial spot cutoff is 180,
-resulting in uniform light distribution.
-.TP
-_const(CONSTANT_ATTENUATION)
-.TP
-_const(LINEAR_ATTENUATION )
-.TP
-_const(QUADRATIC_ATTENUATION)
-_param3 is a single integer or floating-point value that specifies
-one of the three light attenuation factors.
-Integer and floating-point values are mapped directly.
-Only nonnegative values are accepted.
-If the light is positional,
-rather than directional,
-its intensity is attenuated by the reciprocal of the sum of the constant
-factor, the linear factor times the distance between the light
-and the vertex being lighted,
-and the quadratic factor times the square of the same distance.
-The initial attenuation factors are (1, 0, 0),
-resulting in no attenuation.
-.SH NOTES
-It is always the case that _const(LIGHT)$i$ = _const(LIGHT0) + $i$.
-.SH ERRORS
-_const(INVALID_ENUM) is generated if either _param1 or _param2
-is not an accepted value.
-.P
-_const(INVALID_VALUE) is generated if a spot exponent value is specified
-outside the range [0,128],
-or if spot cutoff is specified outside the range [0,90] (except for the
-special value 180),
-or if a negative attenuation factor is specified.
-.P
-_const(INVALID_OPERATION) is generated if _cmnd is executed between
-the execution of
-_cmnd(Begin) and the corresponding execution of _cmnd(End).
