/**
* File: ZTextureAnimation.cpp
* ZResources defined: ZTextureAnimation, ZTextureAnimationParams (XML declaration not supported for
* the latter)
* Purpose: extracting texture animating structures from asset files
* Note: data type is exclusive to Majora's Mask
*
* Structure of data:
* A texture animation consists of a main array of data of the form
* `SS 00 00 0T PPPPPPPP`,
* where `S` is the segment that the functionality is sent to (and read by DLists), `T` is the
* "type" (see below), and `P` is a pointer to the type's subsidiary information, which is
* invariably just above this main array. Details of this subsidiary data are given below.
*
* Segment
* ===
* The segment starts at 1 and is incremented in each entry; the final one is negated, which is used
* as the indication to stop reading. The actual segment the game will use to draw is S + 7.
*
* Types
* ===
* There are 7 values that `T` can take:
* `0`: A single texture scroll (Implemented by Gfx_TexScroll): subsidiary params are given as
* an array with one entry, a struct `XX YY WW HH` containing xStep, yStep, width, height
* (all u8).
*
* `1`: A dual texture scroll (Implementated by Gfx_TwoTexScroll): same as type `0`, but with
* two entries in the params array.
*
* `2`: Color changing: Changes the primColor (with a LOD factor) and envColor
* `KKKK LLLL PPPPPPPP QQQQQQQQ RRRRRRRR`
* - `K` (u16) is the total length of the animation (and in this case, the total number of
* colors)
* - `L` (u16) is seemingly always 0 for this type, and not used in the code
* - `P` segmented pointer to array of augmented primColors
* - `Q` segmented pointer to array of envColors, and can be NULL
* - `R` segmented pointer to array of frameData (u8), which is also seemingly always NULL
* for this type.
*
* envColors take the form `RR GG BB AA` as usual, while primColors have an extra LODFrac
* element: RR GG BB AA LL
*
* `3`: Color changing (LERP): similar to type `2`, but uses linear interpolation. The structure
* is similar to `2`, but
* - `K` is now just the animation length, while
* - `L` is the total number of colors, and
* - the frameData is used to determine which colors to interpolate.
*
* `4`: Color changing (Lagrange interpolation): For extraction purposes identical to type 3.
* Uses a nonlinear interpolation formula to change the colours more smoothly.
*
* `5`: Texture cycle: functions like a gif. Subsidiary params:
* `FFFF 0000 PPPPPPPP QQQQQQQQ`
* where
* - `F` (u16) time between changes in frames
* - `P` pointer to array of segmented pointers to textures to cycle through
* - `Q` array of indices, indicating which texture to use next when a change frame is
* reached. The maximum indicates the number of textures in the texture array.
*
* `6`: This is used to indicate an empty/unimplemented params set. It is ignored by the game's
* function provided that the segment is 0. A generic empty one takes the form
* `00 00 00 06 00000000`,
* and has no extra data.
*
* Implementation
* ===
* - ZTextureAnimation requires a declaration in the XML to extract anything. It handles the main
* array. It uses a POD struct for each entry, and declares references to the params structs.
*
* - ZTextureAnimationParams is not (currently) declarable in an XML. It is a parent class for the
* three classes that handle the various cases:
* - TextureScrollingParams for types `0` and `1`
* - TextureColorChangingParams for types `2`,`3`,`4`
* - TextureCyclingParams for type `5`
* Each of these will declare all its subsidiary arrays, using POD structs.
