-_phead(_param1)
-Specifies a texture environment.
-Must be _const(TEXTURE_ENV).
-_phead(_param2)
-Specifies the symbolic name of a texture environment parameter.
-Accepted values are _const(TEXTURE_ENV_MODE) and _const(TEXTURE_ENV_COLOR).
-_phead(_param3)
-Specifies a pointer to a parameter array that contains
-either a single symbolic constant or an RGBA color.
-.SH DESCRIPTION
-A texture environment specifies how texture values are interpreted
-when a fragment is textured.
-_param1 must be _const(TEXTURE_ENV).
-_param2 can be either _const(TEXTURE_ENV_MODE) or _const(TEXTURE_ENV_COLOR).
-.P
-If _param2 is _const(TEXTURE_ENV_MODE),
-then _param3 is (or points to) the symbolic name of a texture function.
-Four texture functions may be specified:
-_const(MODULATE), 
-_const(DECAL), 
-_const(BLEND), and
-_const(REPLACE).
-.P
-A texture function acts on the fragment to be textured using
-the texture image value that applies to the fragment
-(see _cmnd(TexParameter))
-and produces an RGBA color for that fragment.
-The following table shows how the RGBA color is produced for each
-of the three texture functions that can be chosen.
-$C$ is a triple of color values (RGB) and $A$ is the associated alpha value.
-RGBA values extracted from a texture image are in the range [0,1].
-The subscript $f$ refers to the incoming fragment,
-the subscript $t$ to the texture image,
-the subscript $c$ to the texture environment color,
-and subscript $v$ indicates a value produced by the texture function.
-.P
-A texture image can have up to four components per texture element
-(see _cmnd(TexImage1D), _cmnd(TexImage2D), _cmnd(TexImage3D),
-_cmnd(CopyTexImage1D), and _cmnd(CopyTexImage2D)). 
-In a one-component image,
-$L sub t$ indicates that single component.
-A two-component image uses $L sub t$ and $A sub t$.
-A three-component image has only a color value, $C sub t$.
-A four-component image has both a color value $C sub t$
-and an alpha value $A sub t$.

-If _param2 is _const(TEXTURE_ENV_COLOR),
-_param3 is a pointer to an array that holds an RGBA color consisting of four
-values.
-Integer color components are interpreted linearly such that the most
-positive integer maps to 1.0,
-and the most negative integer maps to -1.0.
-The values are clamped to the range [0,1] when they are specified.
-$C sub c$ takes these four values.
-.P
-_const(TEXTURE_ENV_MODE) defaults to _const(MODULATE) and
-_const(TEXTURE_ENV_COLOR) defaults to (0, 0, 0, 0).
-.SH NOTES
-_const(REPLACE) may only be used if the GL version is 1.1 or greater.
-.P
-Internal formats other than 1, 2, 3, or 4 may only be used if the GL
-version is 1.1 or greater.
-.P
-When the _arbstring(multitexture) extension is supported, _cmnd controls 
-the texture environment for the current active texture unit, selected by 
-_cmnd(ActiveTextureARB).
-.sh ERRORS
-_const(INVALID_ENUM) is generated when _param1 or _param2 is not
-one of the accepted defined values,
-or when _param3 should have a defined constant value
-(based on the value of _param2)
-and does not.
-.P
-_const(INVALID_OPERATION) is generated if _cmnd
-is executed between the execution of _cmnd(Begin)
-and the corresponding execution of _cmnd(End).
