Detailed Description

ViewDependentState to manage lighting, clip planes and texture projection By default assigned to the vsg::View, for standard usage you don't need to create or modify the ViewDependentState If you wish to override the standard lighting support provided by ViewDependentState you can subclass it.

To leverage the state that the ViewDependentState provides you need to set up the graphics pipelines with the vsg::ViewDescriptorSetLayout, and add a vsg::BindViewDescriptorSet to a StateGroup. You don't need to explicitly add these if you have created your scene graph using vsg::Builder or used loaders like vsgXchange::Assimp.
