// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 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.
// 2018-06-08: Misc: Extracted imgui_impl_vulkan.cpp/.h away from the old combined GLFW+Vulkan example.
// 2018-06-08: Vulkan: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
