583 * Animated cursors and icons
584 *
585 * The format of animated cursors and icons is yet another example
586 * of bad design by "The Company". The entire RIFF structure is
587 * flawed by design because it is inconsistent and single minded:
588 * - some tags have lengths attached, others don't. The use of these
589 * non-length tags is absolutely unclear;
590 * - the content of "icon" tags can be both icons and cursors;
591 * - tags lack proper alignment constraints. It seems that everything
592 * is 16bit aligned, but I could not find that in any docu. Just be
593 * prepared to eat anything;
594 * - there are no strict constraints on tag-nesting and the organization
595 * is highly illogical;
596 *
597 * Anyhow, here is the basic structure:
598 * "RIFF" { dword taglength }
599 * "ACON" // What does it do?
600 * "LIST" { dword taglength }
601 * "INFO" // And what does this do?
602 * "INAM" { dword taglength } // Icon/cursor name
603 * {inam data}
604 * "IART" { dword taglength } // The artist
605 * {iart data}
606 * "fram" // Is followed by "icon"s
607 * "icon" { dword taglength } // First frame
608 * { icon/cursor data }
609 * "icon" { dword taglength } // Second frame
610 * { icon/cursor data }
611 * ... // ...
612 * "anih" { dword taglength } // Header structure
613 * { aniheader_t structure }
614 * "rate" { dword taglength } // The rate for each frame
615 * { `steps' dwords }
616 * "seq " { dword taglength } // The frame blit-order
617 * { `steps' dwords }
618 *
619 * Tag length are bytelength without the header and length field (i.e. -8).
620 * The "LIST" tag may occur several times and may encapsulate different
621 * tags. The `steps' is the number of "icon" tags found (actually the
622 * number of steps specified in the aniheader_t structure). The "seq "uence
623 * tag can be ommitted, in which case the sequence is equal to the sequence
624 * of "icon"s found in the file. Also "rate" may be ommitted, in which case
625 * the default from the aniheader_t structure is used.
626 *
627 * An animated cursor puts `.cur' formatted files into each "icon" tag,
628 * whereas animated icons contain `.ico' formatted files.
629 *
630 * Note about the code: Yes, it can be shorter/compressed. Some tags can be
631 * dealt with in the same code. However, this version shows what is going on
632 * and is better debug-able.
