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