TKOpenGl - globally defined clipping planes blink when operating with view
Description
When redrawing the view, the global clipping planes are recalculated for the Model-View state which is one frame behind.
The problem occurred after integration of cameras. This problem is not reproduced on OCCT6.7.0 (integration of new clipping planes) and earlier version.
The clipping planes should be defined after setting up viewer model-view matrices. The test case or draw command should be also provided.
