* \brief A manager for loading, caching, and drawing textures.
|
|
*
|
|
* The `TextureManager` class is responsible for handling texture loading, caching,
|
|
* and rendering in the engine. It provides functions to add, load, and draw textures
|
|
* from files, as well as manage sprite sheets.
|
|
*
|
|
* \sa Textures "Textures" are used to identify textures within the engine.
|
|
* It is expected that they are implemented within the games scope.
