NAME
       glGenerateMipmap - generate mipmaps for a specified texture target

C SPECIFICATION
       void glGenerateMipmap(GLenum target);

PARAMETERS
       target
	   Specifies the target to which the texture whose mimaps to generate is bound.  target
	   must be GL_TEXTURE_1D, GL_TEXTURE_2D, GL_TEXTURE_3D, GL_TEXTURE_1D_ARRAY,
	   GL_TEXTURE_2D_ARRAY or GL_TEXTURE_CUBE_MAP.

DESCRIPTION
       glGenerateMipmap generates mipmaps for the texture attached to target of the active
       texture unit. For cube map textures, a GL_INVALID_OPERATION error is generated if the
       texture attached to target is not cube complete.

       Mipmap generation replaces texel array levels level base + 1 through q with arrays derived
       from the level base array, regardless of their previous contents. All other mimap arrays,
       including the level base array, are left unchanged by this computation.

       The internal formats of the derived mipmap arrays all match those of the level base array.
       The contents of the derived arrays are computed by repeated, filtered reduction of the
       level base array. For one- and two-dimensional texture arrays, each layer is filtered
       independently.

ERRORS
       GL_INVALID_ENUM is generated if target is not one of the accepted texture targets.

       GL_INVALID_OPERATION is generated if target is GL_TEXTURE_CUBE_MAP and the texture bound
       to the GL_TEXTURE_CUBE_MAP target of the active texture unit is not cube complete.
