C SPECIFICATION
       void GLAPIENTRY glDisable( GLenum cap )

PARAMETERS
       cap    Specifies a symbolic constant indicating a GL capability.

DESCRIPTION
       glEnable  and  glDisable  enable  and disable various capabilities.  Use
       glIsEnabled or glGet to determine the current setting of any capability.
       The initial value for each capability with the exception of GL_DITHER is
       GL_FALSE. The initial value for GL_DITHER is GL_TRUE.

       Both glEnable and glDisable take a single argument, cap, which  can  as‐
       sume one of the following values:

       GL_ALPHA_TEST            If enabled, do alpha testing. See glAlphaFunc.

       GL_AUTO_NORMAL           If enabled, generate normal vectors when either
                                GL_MAP2_VERTEX_3 or GL_MAP2_VERTEX_4 is used to
                                generate vertices.  See glMap2.

       GL_BLEND                 If  enabled, blend the incoming RGBA color val‐
                                ues with the values in the color  buffers.  See
                                glBlendFunc.

                                cal  operation  to  the incoming RGBA color and
                                color buffer values. See glLogicOp.

       GL_COLOR_MATERIAL        If enabled, have one or more  material  parame‐
                                ters    track    the    current   color.    See
                                glColorMaterial.

                                incoming RGBA color values.  See glColorTable.

                                on   incoming   RGBA   color    values.     See
                                glConvolutionFilter1D.

       GL_CONVOLUTION_2D        If  enabled, perform a 2D convolution operation
                                on   incoming   RGBA   color    values.     See

                                ues.  See glHistogram.

                                glLight.

       GL_LIGHTING              If enabled, use the current lighting parameters
                                to compute the vertex color or  index.   Other‐
                                wise, simply associate the current color or in‐
                                dex with each vertex. See

       if   GL_ARB_imaging   is   returned  from  glGet  with  an  argument  of
       GL_EXTENSIONS.

       If  GL_ARB_multitexture  is  supported,  GL_TEXTURE_1D,   GL_TEXTURE_2D,
       GL_TEXTURE_3D, GL_TEXTURE_GEN_S, GL_TEXTURE_GEN_T, GL_TEXTURE_GEN_R, and
       GL_TEXTURE_GEN_Q enable or disable the respective state for  the  active
       texture unit specified with glActiveTextureARB.

ERRORS
       GL_INVALID_ENUM is generated if cap is not one of the values listed pre‐
       viously.

       GL_INVALID_OPERATION is generated if glEnable or glDisable  is  executed
       between  the  execution  of  glBegin  and the corresponding execution of
       glEnd.
