 738  * Animated cursors and icons
 739  *
 740  * The format of animated cursors and icons is yet another example
 741  * of bad design by "The Company". The entire RIFF structure is
 742  * flawed by design because it is inconsistent and single minded:
 743  * - some tags have lengths attached, others don't. The use of these
 744  *   non-length tags is absolutely unclear;
 745  * - the content of "icon" tags can be both icons and cursors;
 746  * - tags lack proper alignment constraints. It seems that everything
 747  *   is 16bit aligned, but I could not find that in any docu. Just be
 748  *   prepared to eat anything;
 749  * - there are no strict constraints on tag-nesting and the organization
 750  *   is highly illogical;
 751  *
 752  * Anyhow, here is the basic structure:
 753  * "RIFF" { dword taglength }
 754  *      "ACON"                                  // What does it do?
 755  *      "LIST" { dword taglength }
 756  *              "INFO"                          // And what does this do?

 777  * number of steps specified in the aniheader_t structure). The "seq "uence
 778  * tag can be omitted, in which case the sequence is equal to the sequence
 779  * of "icon"s found in the file. Also "rate" may be omitted, in which case
 780  * the default from the aniheader_t structure is used.
 781  *
 782  * An animated cursor puts `.cur' formatted files into each "icon" tag,
 783  * whereas animated icons contain `.ico' formatted files.
 784  *
 785  * Note about the code: Yes, it can be shorter/compressed. Some tags can be
 786  * dealt with in the same code. However, this version shows what is going on
 787  * and is better debug-able.
