// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2018-03-03: Vulkan: Various refactor, created a couple of ImGui_ImplVulkanH_XXX helper that the example can use and that viewport support will use.
// 2018-03-01: Vulkan: Renamed ImGui_ImplVulkan_Init_Info to ImGui_ImplVulkan_InitInfo and fields to match more closely Vulkan terminology.
// 2018-02-18: Vulkan: Offset projection matrix and clipping rectangle by io.DisplayPos (which will be non-zero for multi-viewport applications).
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback, ImGui_ImplVulkan_Render() calls ImGui_ImplVulkan_RenderDrawData() itself.
