- Introduced a new structure ImGui_ImplSDLSurface3_Quad to represent quads.
- Added functions to detect quads and check for constant colors and linear UVs.
- Enhanced rendering functions to utilize quad detection for faster rendering paths.
- Updated the rendering logic in ImGui_ImplSDLSurface3_RenderDrawData to leverage the new quad rendering capabilities.
- Optimized Makefiles and build scripts to include optimization flags for better performance.
- Created imgui_impl_sdlsurface3.h and corresponding implementation file.
- Added Makefile for building the SDL3 surface example on Linux and macOS.
- Included README.md with build instructions for Windows, Linux, and macOS.
- Added build script for Windows (build_win32.bat) and Visual Studio project files.
- Implemented main application logic in main.cpp to demonstrate ImGui with SDL3 and surface rendering.
