Detailed Description

Class allowing to handle textures lifetime.

Texture manager that supports resource sharing between OpenGL contexts.

FIXME: OpenGL texture can be shared between context of a same context group, so, IN THEORY, we could have a single instance of OGLTextureManager shared between all contexts. We didn't manage to create a group containing all contexts meaning that for the moment one OGLTextureManager is instanced for each context.
