Detailed Description

Class for rectangular screen area abstraction as a location for numerous objects placed one over another.

Placeholders are managed inside some layout. Each placeholder has two pixel group memebers which refer to pixel groups in layout.

ZqbPlaceholder::ZqbPlaceholder	(	ZqbContainer &	container,
		ZqbPixGroup *	pPGX,
		ZqbPixGroup *	pPGY,
