Detailed Description

Toplevel holder of the assets meshes, materials, textures and shaders.

All these assets can be shared among instances of SLScene, SLNode and SLMaterial. Shared assets are meshes (SLMesh), materials (SLMaterial), textures (SLGLTexture) and shader programs (SLGLProgram). One instance of SLAssetManager must be owned and destroyed by the app (see e.g. AppCommon.h).
