+/* GLX protocol templates are named in the following manner. All templates
+ * begin with the string 'glxproto_'. Following is an optional list of
+ * scalar parameters. The scalars are listed as type and number. The most
+ * common being \c enum1 (one scalar enum) and \c enum2 (two scalar enums).
+ *
+ * The final part of the name describes the number of named-type parameters
+ * and how they are passed.
+ * - One or more digits followed by the letter s means
+ * that the specified number of parameters are passed as scalars. The macro
+ * \c glxproto_3s generates a function that takes 3 scalars, such as
+ * \c glVertex3f.
+ * - A capital C follwed by a lower-case v means that a constant
+ * sized vector is passed. Macros of this type take an extra parameter,
+ * which is the size of the vector. The invocation
+ * 'glxproto_Cv(Vertex3fv, X_GLrop_Vertexfv, GLfloat, 3)' would generate the
+ * correct protocol for the \c glVertex3fv function.
+ * - A capital V followed by a lower-case v means that a variable sized
+ * vector is passed. The function generated by these macros will call
+ * a co-function to determine the size of the vector. The name of the
+ * co-function is generated by prepending \c __gl and appending \c _size
+ * to the base name of the function. The invocation
+ * 'glxproto_enum1_Vv(Fogiv, X_GLrop_Fogiv, GLint)' would generate the
+ * correct protocol for the \c glFogiv function.
+ * - One or more digits without a following letter means that a function
+ * taking the specified number of scalar parameters and a function with a
+ * vector parameter of the specified size should be generated. The letter
+ * v is automatically appended to the name of the vector-based function in
+ * this case. The invocation
+ * 'glxproto_3(Vertex3f, X_GLrop_Vertex3fv, GLfloat)' would generate the
+ * correct protocol for both \c glVertex3f and \c glVertex3fv.
+ *
+ * glxproto_void is a special case for functions that take no parameters
+ * (i.e., glEnd).
+ *
+ * An addition form is 'glxvendr_'. This is identical to the other forms
+ * with the exception of taking an additional parameter (to the macro) which
+ * is a vendor string to append to the function name. The invocation
+ * 'glxproto_3(Foo3f, X_GLrop_Foo3fv, GLfloat)' would generate the functions
+ * 'glFoo3fv' and 'glFoo3f', and the invocation
+ * 'glxvendr_3(Foo3f, X_GLrop_Foo3fv, GLfloat, EXT)' would generate the
+ * functions 'glFoo3fvEXT' and 'glFoo3fEXT'.

+ * Somewhere between GLX 1.2 and 1.3 (in SGI's code anyway) the
+ * protocol for glAreTexturesResident, glDeleteTextures, glGenTextures,
+ * and glIsTexture() was changed. Before, calls to these functions
+ * generated protocol for the old GL_EXT_texture_object versions of those
+ * calls. In the newer code, this is actually corrected; calls to the
+ * 1.1 functions generate 1.1 protocol and calls to the EXT functions
+ * generate EXT protocol.
+ * Unfortunately, this correction causes an incompatibility. Specifically,
+ * an updated libGL.so will send protocol requests that the server won't
+ * be able to handle. For example, calling glGenTextures will generate a
+ * BadRequest error.
+ * For now, we'll keep generating EXT protocol from libGL. We'll update
+ * the server to understand both the 1.1 and EXT protocol ASAP. At some point
+ * in the future we'll correct libGL.so as well. That should be a smoother
