42 /* This is a table driven implemetation of the glGet*v() functions.
43 * The basic idea is that most getters just look up an int somewhere
44 * in struct gl_context and then convert it to a bool or float according to
45 * which of glGetIntegerv() glGetBooleanv() etc is being called.
46 * Instead of generating code to do this, we can just record the enum
47 * value and the offset into struct gl_context in an array of structs. Then
48 * in glGet*(), we lookup the struct for the enum in question, and use
49 * the offset to get the int we need.
50 *
51 * Sometimes we need to look up a float, a boolean, a bit in a
52 * bitfield, a matrix or other types instead, so we need to track the
53 * type of the value in struct gl_context. And sometimes the value isn't in
54 * struct gl_context but in the drawbuffer, the array object, current texture
55 * unit, or maybe it's a computed value. So we need to also track
56 * where or how to find the value. Finally, we sometimes need to
57 * check that one of a number of extensions are enabled, the GL
58 * version or flush or call _mesa_update_state(). This is done by
59 * attaching optional extra information to the value description
60 * struct, it's sort of like an array of opcodes that describe extra
61 * checks or actions.
62 *
63 * Putting all this together we end up with struct value_desc below,
64 * and with a couple of macros to help, the table of struct value_desc
65 * is about as concise as the specification in the old python script.
