0030640: Visualization, Graphic3d_Camera - add option creating Projection matrix with [0,1] depth range

Browse Source 
Added new property Graphic3d_Camera::IsZeroToOneDepth() and OpenGl_Caps::useZeroToOneDepth
for activating [0,1] depth range instead of [-1,1] range using glClipControl() within OpenGL 4.5+.
