10 * These helper functions are used for GL functions that take a pointers,
11 * if the size of the arrays that the pointers refer to is not constant.
12 * These helper functions will determine, on a case-by-case basis,
13 * how much space is needed to store the array. If the buffer
14 * parameter is not NULL, they will also pack the data into the given
15 * array.
16 *
17 * Many of the functions included deal with pixel state (Bitmap, DrawPixels,
18 * etc.). In all these cases, when the function instance is stored in a
19 * display list, its data is read from memory (as per the parameters
20 * to PixelStore) and is stored in a tightly packed format (with no
21 * excess row length, no pixels skipped, no rows, skipped, and a byte
22 * alignment).
23 *
24 * When the instances are executed again, care must be taken to ensure
25 * that the PixelStore client state that unpacks them is set to reflect
26 * the tight packing actually used, instead of whatever the current
27 * client state indicates.
28 *
29 * So to do this, client PixelStore state is forced to known values
30 * before any instances in the display list are executed. The client
31 * state is then restored to known values afterwards. (The difficulty
32 * of this is somewhat mollified by the observation that PixelStore
33 * instances affect client state, and cannot be stored in a display list.)
