Summary

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

Description

Current Graphic3d_Camera implementation relies on conventional OpenGL NDC definition with depth range mapped to [-1,1] range (same as for other axes).

There are, however, another convention mapping depth into [0,1] range, adopted by Vulkan and Direct3D graphic APIs.
It is desired providing an option within Graphic3d_Camera computing suitable Projection matrix in this case.
