VulkanSceneGraph-1.1.8, vsgXchange-1.1.4, vsgQt-0.40, vsgImGui-0.6.0 and vsgExamples-1.1.6 releases tagged

[robertosfield]

After a bit delay I'm finally back on the release wagon and have tagged developer releases for all the main VulkanSceneGraph projects. The releases are:

• VulkanSceneGraph-1.1.8
• vsgXchange-1.1.4
• vsgQt-0.4.0
• vsgImGui-0.6.0
• vsgExamples-1.1.6

The biggest changes/additions are the addition of vsg::PolytopeIntersector and a refactor of how the compile traversal manages data transfer, shifting the task to dedicated vsg::TransferTask class that is faster and lowers latency of database paging.

vsgImGui has been updated to work with the latest ImGui-1.91.4 release, and there have been various refinements to vsgXchange, vsgQt and vsgExamples.
