Vulkan backend for Dear ImGui in Beef

Ported from the official Vulkan backend based on commit 5854da10e664312e51acec618267d06b1294ac0b.

Usage

Clone the project into BeefLibs, then in the IDE, right click your workspace and go Add From Installed > ImGuiImplVulkan.
Requires the Bulkan library.

Example:

using ImGui;

namespace Foo {
    class Bar {
        public static void Main() {
            ImGuiImplVulkan.InitInfo info = .() {
                // Fill with Vulkan data
            };

            ImGuiImplVulkan.Init(&info, renderPass);

            // Upload fonts
            {
                // Begin command buffer
                ImGuiImplVulkan.CreateFontsTexture(commandBuffer);
                // End command buffer

                VkSubmitInfo submitInfo = .() {
                    commandBufferCount = 1,
                    pCommandBuffers = commandBuffer
                };
                vkQueueSubmit(queue, 1, &submitInfo, .Null);
                vkDeviceWaitIdle(device);

                ImGuiImplVulkan.DestroyFontUploadObjects();
            }

            ...

            while (true) {
                ...
                ImGuiImplVulkan.NewFrame();
                ...
                ImGui.Render();
                ImGuiImplVulkan.RenderDrawData(ImGui.GetDrawData(), commandBuffer);
                ...
            }

            ...

            ImGuiImplVulkan.Shutdown();
        }
    }
}
