 This class contains cube GL renderer.

 CGLCube initializes the EGL environment and renders off-screen pixmap surfaces. 

 Creation of the pixmap is based on RSgImage resource which is initialized 

 with parameter  TsgImageInfo.iUsage set to EsgUsageOpenGlesTarget|ESgUsageDirectGdiSource.  

 OpenGL ES API is used to reneder content of the pixmap. The result is available as a TSgDrawableId object.
