DESCRIPTION
       Texturing maps a portion of a specified texture image onto each  graphi‐
       cal  primitive  for  which  texturing is enabled.  To enable and disable
       three-dimensional texturing, call glEnable and glDisable  with  argument
       GL_TEXTURE_3D.

       glTexSubImage3D  redefines  a contiguous subregion of an existing three-
       dimensional texture image.  The texels referenced  by  _param11  replace
       the  portion  of  the  existing texture array with x indices _param3 and
       _eqnparam3+_eqnparam6−1,  inclusive,  y  indices   _param4   and   _eqn‐
       Formats  GL_BGR,   and   GL_BGRA   and   types   GL_UNSIGNED_BYTE_3_3_2,
       GL_UNSIGNED_BYTE_2_3_3_REV,                     GL_UNSIGNED_SHORT_5_6_5,
       GL_UNSIGNED_SHORT_5_6_5_REV,                  GL_UNSIGNED_SHORT_4_4_4_4,
       GL_UNSIGNED_SHORT_4_4_4_4_REV,                GL_UNSIGNED_SHORT_5_5_5_1,
       GL_UNSIGNED_SHORT_1_5_5_5_REV,                  GL_UNSIGNED_INT_8_8_8_8,
       GL_UNSIGNED_INT_8_8_8_8_REV,       GL_UNSIGNED_INT_10_10_10_2,       and
       GL_UNSIGNED_INT_2_10_10_10_REV are available only if the GL  version  is
       1.2 or greater.

       When  the  GL_ARB_multitexture  extension  is supported, glTexSubImage3D
       specifies a three-dimensional sub texture for the current texture  unit,
       specified with glActiveTextureARB.

       When  the  GL_ARB_imaging  extension  is  supported, the RGBA components
       specified in _param11 may be processed by  the  imaging  pipeline.   See
       glTexImage3D for specific details.

ERRORS
       GL_INVALID_ENUM is generated if target is not GL_TEXTURE_3D.

       GL_INVALID_OPERATION  is generated if the texture array has not been de‐
       fined by a previous glTexImage3D operation.

       GL_INVALID_VALUE is generated if leve is less than 0.

       GL_INVALID_VALUE may be generated if leve is greater than log2max, where
       max is the returned value of GL_MAX_TEXTURE_SIZE.

       GL_INVALID_VALUE   is   generated  if  _eqnparam3<−b,  (_eqnparam3+_eqn‐
       param6)>(w−b), _eqnparam4<−b, or (_eqnparam4+_eqnparam7)>(h−b), or _eqn‐
       param5<−b,    or   (_eqnparam5+_eqnparam8)>(d−b),   where   w   is   the
       GL_TEXTURE_WIDTH, h is the GL_TEXTURE_HEIGHT, d is the  GL_TEXTURE_DEPTH
       and  b  is  the  border width of the texture image being modified.  Note
       that w, h, and d include twice the border width.

       GL_INVALID_VALUE is generated if _param6, _param7, or  _param8  is  less
       than 0.

       GL_INVALID_ENUM  is  generated if _param9 is not an accepted format con‐
       stant.

       GL_INVALID_ENUM is generated if _param10 is not a type constant.

       GL_INVALID_ENUM is generated if _param10 is GL_BITMAP and _param9 is not
       GL_COLOR_INDEX.

       GL_INVALID_OPERATION is generated if glTexSubImage3D is executed between
       the execution of glBegin and the corresponding execution of glEnd.

       GL_INVALID_OPERATION   is   generated   if   _param10    is    one    of
       GL_UNSIGNED_BYTE_3_3_2,                      GL_UNSIGNED_BYTE_2_3_3_REV,
       GL_UNSIGNED_SHORT_5_6_5, or GL_UNSIGNED_SHORT_5_6_5_REV and  _param9  is
       glActiveTextureARB,         glCopyTexImage1D,          glCopyTexImage2D,
       glCopyTexSubImage1D,      glCopyTexSubImage2D,      glCopyTexSubImage3D,
