36 /* This is a table driven implemetation of the glGet*v() functions.
37 * The basic idea is that most getters just look up an int somewhere
38 * in GLcontext and then convert it to a bool or float according to
39 * which of glGetIntegerv() glGetBooleanv() etc is being called.
40 * Instead of generating code to do this, we can just record the enum
41 * value and the offset into GLcontext in an array of structs. Then
42 * in glGet*(), we lookup the struct for the enum in question, and use
43 * the offset to get the int we need.
44 *
45 * Sometimes we need to look up a float, a boolean, a bit in a
46 * bitfield, a matrix or other types instead, so we need to track the
47 * type of the value in GLcontext. And sometimes the value isn't in
48 * GLcontext but in the drawbuffer, the array object, current texture
49 * unit, or maybe it's a computed value. So we need to also track
50 * where or how to find the value. Finally, we sometimes need to
51 * check that one of a number of extensions are enabled, the GL
52 * version or flush or call _mesa_update_state(). This is done by
53 * attaching optional extra information to the value description
54 * struct, it's sort of like an array of opcodes that describe extra
55 * checks or actions.
56 *
57 * Putting all this together we end up with struct value_desc below,
58 * and with a couple of macros to help, the table of struct value_desc
59 * is about as concise as the specification in the old python script.
