51 /* This is a table driven implemetation of the glGet*v() functions.
52 * The basic idea is that most getters just look up an int somewhere
53 * in struct gl_context and then convert it to a bool or float according to
54 * which of glGetIntegerv() glGetBooleanv() etc is being called.
55 * Instead of generating code to do this, we can just record the enum
56 * value and the offset into struct gl_context in an array of structs. Then
57 * in glGet*(), we lookup the struct for the enum in question, and use
58 * the offset to get the int we need.
59 *
60 * Sometimes we need to look up a float, a boolean, a bit in a
61 * bitfield, a matrix or other types instead, so we need to track the
62 * type of the value in struct gl_context. And sometimes the value isn't in
63 * struct gl_context but in the drawbuffer, the array object, current texture
64 * unit, or maybe it's a computed value. So we need to also track
65 * where or how to find the value. Finally, we sometimes need to
66 * check that one of a number of extensions are enabled, the GL
67 * version or flush or call _mesa_update_state(). This is done by
68 * attaching optional extra information to the value description
69 * struct, it's sort of like an array of opcodes that describe extra
70 * checks or actions.
71 *
72 * Putting all this together we end up with struct value_desc below,
73 * and with a couple of macros to help, the table of struct value_desc
74 * is about as concise as the specification in the old python script.
