/**
* This is the namespace of the LastExpress engine.
*
* Status of this engine:
* The game is playable but still very buggy and missing crucial functionality:
* - Resources: classes for the resource formats used by the game are mostly
* complete (subtitles integration/cursor transparency are missing)
* - Display: basic graphic manager functionality is implemented (transitions
* and dirty rects handling are missing)
* - Menu/Navigation: menu is done and navigation/hotspot handling are also
* mostly implemented (with remaining bugs)
* - Logic: all the hardcoded AI logic has been implemented, as well as the
* shared entity code for drawing/handling of entities.
* - Sound: most of the sound queue functionality is still missing
* - Savegame: almost all the savegame code is still missing.
*
* Maintainers:
* littleboy, jvprat, clone2727
*
* Supported games:
* - The Last Express
