// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-01-05: Vulkan: Helper for creating render pass uses ImGui_ImplVulkanH_Window::AttachmentDesc to create render pass. Removed ClearEnabled. (#9152)
// 2025-11-24: Vulkan: Helper for creating a swap-chain (used by examples and multi-viewports) selects VkSwapchainCreateInfoKHR's compositeAlpha based on cap.supportedCompositeAlpha. (#8784)
// 2025-10-15: Vulkan: Added IMGUI_IMPL_VULKAN_VOLK_FILENAME to configure path to volk.h header. (#9008)
// 2025-09-26: *BREAKING CHANGE*: moved some fields in ImGui_ImplVulkan_InitInfo: init_info.RenderPass --> init_info.PipelineInfoMain.RenderPass, init_info.Subpass --> init_info.PipelineInfoMain.Subpass, init_info.MSAASamples --> init_info.PipelineInfoMain.MSAASamples, init_info.PipelineRenderingCreateInfo --> init_info.PipelineInfoMain.PipelineRenderingCreateInfo.
