Add SDL3 surface backend for ImGui example
- 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.

# How to Build
|
||||
|
||||
## Windows with Visual Studio's IDE
|
||||
|
||||
Use the provided project file (`example_sdl3_surface.vcxproj`) or open `imgui_examples.sln`.
|
||||
|
||||
## Windows with Visual Studio's CLI
|
||||
|
||||
Use `build_win32.bat` or directly:
|
||||
```bat
|
||||
set SDL3_DIR=path_to_your_sdl3_folder
|
||||
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_sdlsurface3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_surface.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x86 SDL3.lib /subsystem:console
|
||||
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_sdlsurface3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_surface.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x64 SDL3.lib /subsystem:console
|
||||
```
|
||||
|
||||
## Linux and similar Unixes
|
||||
|
||||
Use the provided `Makefile` or directly:
|
||||
```sh
|
||||
c++ `pkg-config --cflags sdl3` -I .. -I ../.. -I ../../backends \
|
||||
main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_sdlsurface3.cpp ../../imgui*.cpp \
|
||||
-ldl `pkg-config --libs sdl3`
|
||||
```
|
||||
|
||||
## macOS
|
||||
|
||||
Use the provided `Makefile` or directly:
|
||||
```sh
|
||||
brew install sdl3
|
||||
c++ `pkg-config --cflags sdl3` -I .. -I ../.. -I ../../backends \
|
||||
main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_sdlsurface3.cpp ../../imgui*.cpp \
|
||||
-framework Cocoa -framework IOKit -framework CoreVideo `pkg-config --libs sdl3`
