|
|

|
|
* ANIMSIZE_UNKNOWN:
|
|
* - Animation data entry size is unknown (Used as an error).
|
|
*
|
|
* ANIMSIZE_23:
|
|
* - Animation data entry size is 23 bytes.
|
|
* - Used at least by 0.11.0 and 0.11.1 releases of ScummVM.
|
|
* - Introduced in revision 21772, stopped using in revision 31444.
|
|
*
|
|
* ANIMSIZE_30_PTRS_BROKEN:
|
|
* - Animation data entry size is 30 bytes.
|
|
* - Data and mask pointers in the saved structs are always NULL.
|
|
* - Introduced in revision 31453, stopped using in revision 32073.
|
|
*
|
|
* ANIMSIZE_30_PTRS_INTACT:
|
|
* - Animation data entry size is 30 bytes.
|
|
* - Data and mask pointers in the saved structs are intact,
|
|
* so you can test them for equality or inequality with NULL
|
|
* but don't try using them for anything else, it won't work.
|
|
* - Introduced in revision 31444, got broken in revision 31453,
|
|
* got fixed in revision 32073 and used after that.
|
|
*
|
|
* TEMP_OS_FORMAT:
|
|
* - Temporary Operation Stealth savegame format.
|
|
* - NOT backward compatible and NOT to be supported in the future.
|
|
* This format should ONLY be used during development and abandoned
|
|
* later in favor of a better format!
