/* This is a table driven implementation 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.
