  77 The various attributes for param and glx have the meanings listed below.
  78 When adding new functions, please annote them correctly.  In most cases this
  79 will just mean adding a '<glx ignore="true"/>' tag.
  80
  81 param:
  82      name - name of the parameter
  83      type - fully qualified type (e.g., with "const", etc.)
  84      client_only - boolean flag set on parameters which are interpreted only
  85          by the client and are not present in the protocol encoding (e.g.,
  86          the stride parameters to Map1f, etc.)
  87      count - for counted arrays (e.g., the 'lists' parameter to glCallLists),
  88          the parameter or literal that represents the count.  For functions
  89          like glVertex3fv it will be a litteral, for others it will be one of
  90          the parameters.
  91      counter - this parameter is a counter that will be referenced by the
  92          'count' attribute in another parameter.
  93      count_scale - literal value scale factor for the 'count' attribute.
  94          See ProgramParameters4dvNV for an example.
  95      output - this parameter is used to store the output of the function.
  96      variable_param - name of parameter used to determine the number of
  97          elements referenced by this parameter.  This should be the name of a
  98          single enum parameter.  Most of the gl*Parameter[if]v functions use
  99          this.  Additionally, the enums that can be passed should be properly
 100          annotated.
 101      img_width / img_height / img_depth / img_extent - name of parameters
 102          (or hardcoded integer) used for the dimensions of pixel data.
 103      img_xoff / img_yoff / img_zoff / img_woff - name of parameters used
 104          for x, y, z, and w offsets of pixel data.
 105      img_format - name of parameter used as the pixel data format.
 106      img_type - name of parameter used as the pixel data type.
 107      img_target - name of parameter used as a texture target.  Non-texture
 108         pixel data should hardcode 0.
 109      img_send_null - boolean flag to determine if blank pixel data should
 110         be sent when a NULL pointer is passed.  This is only used by
 111         TexImage1D and TexImage2D.
 112      img_null_flag - boolean flag to determine if an extra flag is used to
 113         determine if a NULL pixel pointer was passed.  This is used by
 114         TexSubImage1D, TexSubImage2D, TexImage3D and others.
 115      img_pad_dimensions - boolean flag to determine if dimension data and
 116         offset data should be padded to the next even number of dimensions.
 117         For example, this will insert an empty "height" field after the
 118         "width" field in the protocol for TexImage1D.
 119
 120 glx:
 121      rop - Opcode value for "render" commands
 122      sop - Opcode value for "single" commands
 123      vendorpriv - Opcode value for vendor private (or vendor private with
 124          reply) commands
 125      large - set to "true" of the render command can use RenderLarge protocol.
 126      doubles_in_order - older commands always put GLdouble data at the
 127          start of the render packet.  Newer commands (e.g.,
 128          ProgramEnvParameter4dvARB) put the in the order that they appear
 129          in the parameter list.
 130      always_array - some single commands take reply data as an array or as
 131          return value data (e.g., glGetLightfv).  Other single commands take
 132          reply data only as an array (e.g., glGetClipPlane).
 133      handcode - some functions are just too complicated to generate
 134          (e.g., glSeperableFilter2D) or operate only on client-side data
 135          (e.g., glVertexPointer) and must be handcoded.
 136      ignore - some functions have an entry in the dispatch table, but aren't
 137          suitable for protocol implementation (e.g., glLockArraysEXT).  This
 138          also applies to functions that don't have any GLX protocol specified
 139          (e.g., glGetFogFuncSGIS).
