(#914, #5738). +// 2022-01-20: Vulkan: Added support for ImTextureID as VkDescriptorSet. User need to call ImGui_ImplVulkan_AddTexture(). Building for 32-bit targets requires '#define ImTextureID ImU64'. (#914). +// 2021-10-15: Vulkan: Call vkCmdSetScissor() at the end of render a full-viewport to reduce likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling vkCmdSetScissor() explicitly every frame. +// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX). +// 2021-03-22: Vulkan: Fix mapped memory validation error when buffer sizes are not multiple of VkPhysicalDeviceLimits::nonCoherentAtomSize. +// 2021-02-18: Vulkan: Change blending equation to preserve alpha in output buffer. +// 2021-01-27: Vulkan: Added support for custom function load and IMGUI_IMPL_VULKAN_NO_PROTOTYPES by using ImGui_ImplVulkan_LoadFunctions(). +// 2020-11-11: Vulkan: Added support for specifying which subpass to reference during VkPipeline creation. +// 2020-09-07: Vulkan: Added VkPipeline parameter to ImGui_ImplVulkan_RenderDrawData (default to one passed to ImGui_ImplVulkan_Init). +// 2020-05-04: Vulkan: Fixed crash if initial frame has no vertices. +// 2020-04-26: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData didn't have vertices. +// 2019-08-01: Vulkan: Added support for specifying multisample count. Set ImGui_ImplVulkan_InitInfo::MSAASamples to one of the VkSampleCountFlagBits values to use, default is non-multisampled as before. +// 2019-05-29: Vulkan: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag. +// 2019-04-30: Vulkan: Added support for special ImDrawCallback_ResetRenderState callback to reset render state. +// 2019-04-04: *BREAKING CHANGE*: Vulkan: Added ImageCount/MinImageCount fields in ImGui_ImplVulkan_InitInfo, required for initialization (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). Added ImGui_ImplVulkan_SetMinImageCount(). +// 2019-04-04: Vulkan: Added VkInstance argument to ImGui_ImplVulkanH_CreateWindow() optional helper. +// 2019-04-04: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like. +// 2019-04-01: Vulkan: Support for 32-bit index buffer (#define ImDrawIdx unsigned int). +// 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 backends. +// 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. +// 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. +// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback, ImGui_ImplVulkan_Render() calls ImGui_ImplVulkan_RenderDrawData() itself. +// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves. +// 2017-05-15: Vulkan: Fix scissor offset being negative. Fix new Vulkan validation warnings. Set required depth member for buffer image copy. +// 2016-11-13: Vulkan: Fix validation layer warnings and errors and redeclare gl_PerVertex. +// 2016-10-18: Vulkan: Add location decorators & change to use structs as in/out in glsl, update embedded spv (produced with glslangValidator -x). Null the released resources. +// 2016-08-27: Vulkan: Fix Vulkan example for use when a depth buffer is active. + +#include "imgui.h" +#ifndef IMGUI_DISABLE +#include "imgui_impl_vulkan.h" +#include + +// Visual Studio warnings +#ifdef _MSC_VER +#pragma warning (disable: 4127) // condition expression is constant +#endif + +// Reusable buffers used for rendering 1 current in-flight frame, for ImGui_ImplVulkan_RenderDrawData() +// [Please zero-clear before use!] +struct ImGui_ImplVulkanH_FrameRenderBuffers +{ + VkDeviceMemory VertexBufferMemory;
