0024224: Suspicious logics in changing clipping planes at OpenGl_Structure

Browse Source 
1) Resolved buggy situation of shared clip planes between view and structure;
2) Added clipping plane equation space identification - to be used with shaders;
3) Code refactoring to resolve performance issue reported by 0024189;
4) Attachment of stencil buffer to FBO.

Added test case bugs/vis/bug24224
