Detailed Description

Interfaces and wrapper classes for managing OpenGL contexts.

Use can the GL::Context interface and its concrete platform-dependent specializations such as GL::ContextWindows or GL::ContextGLX to perform manual OpenGL context management.

The GL::ContextManager singleton class provides you with a more high-level interface to access, and create OpenGL contexts and have them managed by the ImFusion SDK. This interface is particularly useful if you are working in a multithreaded environment and/or need to use OpenGL context sharing.

The GL::InstanceManager interface enables you transparently manage a single instance of a class for each OpenGL context. This is a powerful feature to avoid constant reallocation of your class while at the same time avoiding race conditions (given that there is a 1-to-1 mapping between OpenGL contexts and threads) or issues if an OpenGL object is not shareable between contexts (such as VAOs).
