static cOglOutputFb *	OutputFramebuffer = NULL
	main OSD output framebuffer - this keeps our finished "OSD" (one per OSD)

Private Attributes
cOglFb *	m_pBufferFramebuffer = nullptr
	all pixmaps are composed onto this framebuffer after each other, before this one is blit onto the OSD output framebuffer
std::shared_ptr< cOglThread >	m_pOglThread
	pointer to thread, which executes the commands
cVector< cOglPixmap * >	m_pOglPixmaps
	array of pixmaps
bool	m_isSubtitleOsd
	true, if this is a subtitle osd
cSize	m_maxPixmapSize
	maximum allowed size of a pixmap (depends on the maximum OpenGL texture size)
cRect	m_pDirtyViewport
	the dirty viewport
