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