/**
* Cutscene scripts are arrays of `CutsceneData` words, including bit-packed integers and floats.
*
* Most command macros have unused arguments. This is to account for the vanilla assets setting specific values
* that don't end up being used by any code. They can safely be set to anything, as they aren't used in the
* implementation.
*
* It is believed the original tool used for cutscenes handled most commands the same way, using similar
* fields, and the code would have accessed them using common structs. Given this, the unused values observed in vanilla
* assets may appear to map to a variable that makes sense, even if it doesn't end up being used in the code. It
* probably isn't garbage data.
*
* This codebase goes with specialized structs and macros to make it easier to follow the code.
* Note this common struct design is still partially reflected in all commands having a `startFrame` and `endFrame`,
* when sometimes only the `startFrame` matters (as documented).

/**
* CMD_F expects an (IEEE 754) encoded float (colloquially "in hex", such as `0x42280000`),
* rather than a C float literal (such as `42.0f`).
* Float literals cannot be used because cutscenes are arrays of union type CutsceneData, which may contain integers and floats.
* Regardless of CutsceneData having a float member, initializing with a float will cast the float to s32.
* Designated initializers (added in C99) would solve this problem but are not supported by IDO (C89 and some extensions).
