642 * Animated cursors and icons
644 * The format of animated cursors and icons is yet another example
645 * of bad design by "The Company". The entire RIFF structure is
646 * flawed by design because it is inconsistent and single minded:
647 * - some tags have lengths attached, others don't. The use of these
648 * non-length tags is absolutely unclear;
649 * - the content of "icon" tags can be both icons and cursors;
650 * - tags lack proper alignment constraints. It seems that everything
651 * is 16bit aligned, but I could not find that in any docu. Just be
652 * prepared to eat anything;
653 * - there are no strict constraints on tag-nesting and the organization
654 * is highly illogical;
656 * Anyhow, here is the basic structure:
657 * "RIFF" { dword taglength }
658 * "ACON" // What does it do?
659 * "LIST" { dword taglength }
660 * "INFO" // And what does this do?
661 * "INAM" { dword taglength } // Icon/cursor name
663 * "IART" { dword taglength } // The artist
665 * "fram" // Is followed by "icon"s
666 * "icon" { dword taglength } // First frame
667 * { icon/cursor data }
668 * "icon" { dword taglength } // Second frame
669 * { icon/cursor data }
671 * "anih" { dword taglength } // Header structure
672 * { aniheader_t structure }
673 * "rate" { dword taglength } // The rate for each frame
675 * "seq " { dword taglength } // The frame blit-order
678 * Tag length are bytelength without the header and length field (i.e. -8).
679 * The "LIST" tag may occur several times and may encapsulate different
680 * tags. The `steps' is the number of "icon" tags found (actually the
681 * number of steps specified in the aniheader_t structure). The "seq "uence
682 * tag can be omitted, in which case the sequence is equal to the sequence
683 * of "icon"s found in the file. Also "rate" may be omitted, in which case
684 * the default from the aniheader_t structure is used.
686 * An animated cursor puts `.cur' formatted files into each "icon" tag,
687 * whereas animated icons contain `.ico' formatted files.
689 * Note about the code: Yes, it can be shorter/compressed. Some tags can be
690 * dealt with in the same code. However, this version shows what is going on
691 * and is better debug-able.
