- Added IRenderer interface to define abstract rendering operations, decoupling application logic from specific rendering APIs. - Implemented SDL2Renderer class, providing concrete methods for texture management, rendering primitives, and lifecycle management using SDL2. - Introduced texture creation, updating, and destruction methods, along with rendering functions to clear the screen and present frames. - Enhanced backend access for third-party library integration, ensuring flexibility in rendering operations.

* @brief A concrete implementation of the IRenderer interface using SDL2.
|

*
|
|
* This class encapsulates all rendering logic that is specific to the SDL2_render API.
|
|
* It translates the abstract calls from the IRenderer interface into concrete SDL2 commands.
|
|
* This is the first step in abstracting the renderer, allowing the rest of the application
|
|
* to be independent of SDL2.
