Summary0030631: Visualization - Vulkan graphic driver prototype
DescriptionIt is proposed writing a Vulkan graphic driver prototype as alternative to OpenGl_GraphicDriver.

TODO:
- [0030635] Move functionality, not specific to OpenGL from TKOpenGl to TKV3d.
  This might include OpenGl_Layer and partial of OpenGl_ShaderManager.
- [0030640] Handle [0,1] depth range used by Vulkan, different from [-1,1] used by OpenGL. Note that NDC [-1,1] range is also pre-considered by various OCCT algorithms using Graphic3d_Camera (projection routines), including selection.
- Handle right-hand coordinate system in Vulkan (contrary to left-hand in OpenGL); (0,0) means top-left viewport corner in Vulkan rather than bottom-left corner in OpenGL. Since OCCT follows OpenGL coordinate system (including 2D presentations), it is undesirable changing convention and instead - flip image vertically during rendering.
- Migrate uniforms to uniform blocks within GLSL programs with embedded bindings and locations required by SPIR-V. This might include Matrix block, Standard Material block, Standard Light Sources block, PBR Material Block, Clipping Planes block, etc. GPU Resource manager should allocate large UBOs for multiple aspects, so that dynamic variables will be passed via offset in UBO to pipeline. SynchronizeAspects should access UBOs via sharable interface, probably generating map keys for reusing equal materials / transformations in the same way as TKOpenGl shares textures.
- Graphic3d_Buffer can be allocated directly accessible for GPU, when integrated GPU is used to avoid extra memory copies. This should be optional (application should NOT modify this memory while rendering), but algorithms like StdPrs_ShadedShape are designed to create Graphic3d_Buffer on-the-fly, so that these presentation builders can benefit on integrated GPUs.
- Retrieve Vulkan function pointers table.
  AMD publications claim that CPU overhead due to proxy vulkan-1.dll is not negligible (1-5%).
- Implement vulkan-1.dll loader to handle obsolete systems without Vulkan drivers.
- Vulkan_Device to search for known OpenGL context device.
  It could be particularly useful retrieving memory requirements using Vulkan API even while working with OpenGL API (where this information is unavailable) to estimate properly GPU memory usage by resources taking into account also various hardware-specific alignment limits.
- Redesign Shader Manager to be able generating standard GLSL programs without building OCCT through Tcl/CMake scripts. Generate SPIR-V shaders using this mechanism during OCCT project generation (to avoid bloating OCCT git with binaries).
- Is it possible loading the same Vulkan device as automatically returned by OpenGL (e.g. device connected to the main display)?
