Detailed Description

Internal structure used as additional sprite header.

This data is put at the end of the main image data of the sprite. This allows the library to stay backward compatible with old sprites created before this structure existed.

The existence of the structure in the sprite can be checked via SPRITE_FLAGS_EXT.
