This is supported by OpenGL, and on Vulkan with VK_EXT_primitive_topology_list_restart. On Vulkan, all drivers are known to support this even without VK_EXT_primitive_topology_list_restart. On D3D, primitive restart is only supported for strip topologies. Previously, RenderDoc specifically disabled primitive restart for non-strip topologies. In this change, that is no longer done. If the app enables primitive restart, so will RenderDoc behave accordingly. It would be the responsibility of the app to avoid primitive restart if the API doesn't allow it.
