This includes the lua, but we're not documenting this yet. Want to be sure this works without it blowing up. ...I think some work on the editor will be needed here.

/* This stores a single note pattern for a song.

*
|
|
* We can have too much data to keep everything decompressed as NoteData, so most
|
|
* songs are kept in memory compressed as SMData until requested. NoteData is normally
|
|
* not requested casually during gameplay; we can move through screens, the music
|
|
* wheel, etc. without touching any NoteData.
|
|
*
|
|
* To save more memory, if data is cached on disk, read it from disk on demand. Not
|
|
* all Steps will have an associated file for this purpose. (Profile edits don't do
|
|
* this yet.)
|
|
*
|
|
* Data can be on disk (always compressed), compressed in memory, and uncompressed in
|
|
* memory. */
