// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2019-02-16: Vulkan: Viewport and clipping rectangles correctly using draw_data->FramebufferScale to allow retina display.
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
// 2018-08-25: Vulkan: Fixed mishandled VkSurfaceCapabilitiesKHR::maxImageCount=0 case.
// 2018-06-22: Inverted the parameters to ImGui_ImplVulkan_RenderDrawData() to be consistent with other bindings.
