+/* This is a table driven implemetation of the glGet*v() functions.
+ * The basic idea is that most getters just look up an int somewhere
+ * in struct gl_context and then convert it to a bool or float according to
+ * which of glGetIntegerv() glGetBooleanv() etc is being called.
+ * Instead of generating code to do this, we can just record the enum
+ * value and the offset into struct gl_context in an array of structs. Then
+ * in glGet*(), we lookup the struct for the enum in question, and use
+ * the offset to get the int we need.
+ *
+ * Sometimes we need to look up a float, a boolean, a bit in a
+ * bitfield, a matrix or other types instead, so we need to track the
+ * type of the value in struct gl_context. And sometimes the value isn't in
+ * struct gl_context but in the drawbuffer, the array object, current texture
+ * unit, or maybe it's a computed value. So we need to also track
+ * where or how to find the value. Finally, we sometimes need to
+ * check that one of a number of extensions are enabled, the GL
+ * version or flush or call _mesa_update_state(). This is done by
+ * attaching optional extra information to the value description
+ * struct, it's sort of like an array of opcodes that describe extra
+ * checks or actions.
+ *
+ * Putting all this together we end up with struct value_desc below,
+ * and with a couple of macros to help, the table of struct value_desc
+ * is about as concise as the specification in the old python script.
