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