Hide the LastSubpass in Vulkan's state from UI (#1268)
Hide the LastSubpass in Vulkan's state from UI (#1268)

When a user clicks on a subcommand, LastSubpass will not show the
current subpass but the last subpass of the whole renderpass. This is
also because of the early terminator of Vulkan which appends extra
vkCmdNextSubpass.
