+ /* Animation compression page format (version 1):
+ *
+ * Animation uses bitwidth based compression separated into small pages. The intention is that pages fit easily in the cache, so decoding is cache efficient.
+ * The page-based nature also makes future animation streaming from disk possible.
+ *
+ * Actual format:
+ *
+ * num_compressed_tracks = bounds.size()
+ * header : (x num_compressed_tracks)
+ * -------
+ * timeline_keys_offset : uint32_t - offset to time keys
+ * timeline_size : uint32_t - amount of time keys
+ * data_keys_offset : uint32_t offset to key data
+ *
+ * time key (uint32_t):
+ * ------------------
+ * frame : bits 0-15 - time offset of key, computed as: page.time_offset + frame * (1.0/fps)
+ * data_key_offset : bits 16-27 - offset to key data, computed as: data_keys_offset * 4 + data_key_offset
+ * data_key_count : bits 28-31 - amount of data keys pointed to, computed as: data_key_count+1 (max 16)
+ *
+ * data key:
+ * ---------
+ * X / Blend Shape : uint16_t - X coordinate of XYZ vector key, or Blend Shape value. If Blend shape, Y and Z are not present and can be ignored.
+ * Y : uint16_t
+ * Z : uint16_t
+ * If data_key_count+1 > 1 (if more than 1 key is stored):
+ * data_bitwidth : uint16_t - This is only present if data_key_count > 1. Contains delta bitwidth information.
+ * X / Blend Shape delta bitwidth: bits 0-3 -
+ * if 0, nothing is present for X (use the first key-value for subsequent keys),
+ * else assume the number of bits present for each element (+ 1 for sign). Assumed always 16 bits, delta max signed 15 bits, with underflow and overflow supported.
+ * Y delta bitwidth : bits 4-7
+ * Z delta bitwidth : bits 8-11
+ * FRAME delta bitwidth : 12-15 bits - always present (obviously), actual bitwidth is FRAME+1
+ * Data key is 4 bytes long for Blend Shapes, 8 bytes long for pos/rot/scale.
+ *
+ * delta keys:
+ * -----------
+ * Compressed format is packed in the following format after the data key, containing delta keys one after the next in a tightly bit packed fashion.
+ * FRAME bits -> X / Blend Shape Bits (if bitwidth > 0) -> Y Bits (if not Blend Shape and Y Bitwidth > 0) -> Z Bits (if not Blend Shape and Z Bitwidth > 0)
+ *
+ * data key format:
+ * ----------------
+ * Decoding keys means starting from the base key and going key by key applying deltas until the proper position is reached needed for interpolation.
+ * Resulting values are uint32_t
+ * data for X / Blend Shape, Y and Z must be normalized first: unorm = float(data) / 65535.0
+ * **Blend Shape**: (unorm * 2.0 - 1.0) * Compression::BLEND_SHAPE_RANGE
+ * **Pos/Scale**: unorm_vec3 * bounds[track].size + bounds[track].position
+ * **Rotation**: Quaternion(Vector3::octahedron_decode(unorm_vec3.xy),unorm_vec3.z * Math_PI * 2.0)
+ * **Frame**: page.time_offset + frame * (1.0/fps)
