What problem does it solve?

Set up an SDL3 GPU application using the callback architecture to streamline starting a new program that renders with the GPU API.

Core Features & Use Cases

• Callback-based main loop pattern: define SDL_MAIN_USE_CALLBACKS 1 before including headers to replace the traditional main loop.
• Unified GPU device creation: initialize the GPU device across Vulkan, DX12, and Metal with debug/validation enabled.
• Window and swapchain management: create a window and associate it with the GPU device to establish the swapchain.
• GPU swapchain configuration: configure sRGB swapchains and log the chosen backend for correct color handling.
• Per-frame rendering workflow: acquire command buffers, render, and present each frame using the SDL GPU pipeline.

Quick Start

Create a new SDL3 GPU project and adopt the four-callback pattern to initialize the window, GPU device, and resources.
