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