<!--
The various attributes for param and glx have the meanings listed below.
When adding new functions, please annote them correctly.  In most cases this
will just mean adding a '<glx ignore="true"/>' tag.

param:
     name - name of the parameter
     type - fully qualified type (e.g., with "const", etc.)
     client_only - boolean flag set on parameters which are interpreted only
         by the client and are not present in the protocol encoding (e.g.,
	 the stride parameters to Map1f, etc.)
     count - for counted arrays (e.g., the 'lists' parameter to glCallLists),
         the parameter or literal that represents the count.  For functions
         like glVertex3fv it will be a litteral, for others it will be one of
         the parameters.
     counter - this parameter is a counter that will be referenced by the
         'count' attribute in another parameter.
     count_scale - literal value scale factor for the 'count' attribute.
         See ProgramParameters4dvNV for an example.
     output - this parameter is used to store the output of the function.
     variable_param - name of parameter used to determine the number of
         elements referenced by this parameter.  This should be the name of a
         single enum parameter.  Most of the gl*Parameter[if]v functions use
         this.  Additionally, the enums that can be passed should be properly
         annotated.
     img_width / img_height / img_depth / img_extent - name of parameters
         (or hardcoded integer) used for the dimensions of pixel data.
     img_xoff / img_yoff / img_zoff / img_woff - name of parameters used
         for x, y, z, and w offsets of pixel data.
     img_format - name of parameter used as the pixel data format.
     img_type - name of parameter used as the pixel data type.
     img_target - name of parameter used as a texture target.  Non-texture
        pixel data should hardcode 0.
     img_send_null - boolean flag to determine if blank pixel data should
        be sent when a NULL pointer is passed.  This is only used by
        TexImage1D and TexImage2D.
     img_null_flag - boolean flag to determine if an extra flag is used to
        determine if a NULL pixel pointer was passed.  This is used by
        TexSubImage1D, TexSubImage2D, TexImage3D and others.
     img_pad_dimensions - boolean flag to determine if dimension data and
        offset data should be padded to the next even number of dimensions.
        For example, this will insert an empty "height" field after the
        "width" field in the protocol for TexImage1D.

glx:
     rop - Opcode value for "render" commands
     sop - Opcode value for "single" commands
     vendorpriv - Opcode value for vendor private (or vendor private with
         reply) commands
     large - set to "true" of the render command can use RenderLarge protocol.
     doubles_in_order - older commands always put GLdouble data at the
         start of the render packet.  Newer commands (e.g., 
         ProgramEnvParameter4dvARB) put the in the order that they appear
         in the parameter list.
     always_array - some single commands take reply data as an array or as
         return value data (e.g., glGetLightfv).  Other single commands take
         reply data only as an array (e.g., glGetClipPlane).
     handcode - some functions are just too complicated to generate 
         (e.g., glSeperableFilter2D) or operate only on client-side data
         (e.g., glVertexPointer) and must be handcoded.
     ignore - some functions have an entry in the dispatch table, but aren't
         suitable for protocol implementation (e.g., glLockArraysEXT).  This
         also applies to functions that don't have any GLX protocol specified
         (e.g., glGetFogFuncSGIS).
