Rebuild trinity visualizer from bare SDL and OpenGL to using Raylib. Added Code for serial parsing on linux. Current functionality reads incoming quaternion packet data coming in over serial and displays the values and also visualizes with a cube, connect and disconnect is implemented. Essentially rebuild the functionality of the old version with added linux support.

# How to Build
## Windows with Visual Studio's IDE
Use the provided project file (.vcxproj). Add to solution (imgui_examples.sln) if necessary.
## Windows with Visual Studio's CLI
Use build_win32.bat or directly:
```
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_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_opengl3.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x86 SDL3.lib opengl32.lib /subsystem:console
# ^^ include paths ^^ source files ^^ output exe ^^ output dir ^^ libraries
# or for 64-bit:
cl /Zi /MD /utf-8 /I.. /I..\.. /I%SDL3_DIR%\include main.cpp ..\..\backends\imgui_impl_sdl3.cpp ..\..\backends\imgui_impl_opengl3.cpp ..\..\imgui*.cpp /FeDebug/example_sdl3_opengl3.exe /FoDebug/ /link /libpath:%SDL3_DIR%\lib\x64 SDL3.lib SDL2mainopengl32.lib /subsystem:console
```
## Linux and similar Unixes
Use our Makefile or directly:
```
c++ `sdl3-config --cflags` -I .. -I ../.. -I ../../backends
main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
`sdl3-config --libs` -lGL -ldl
```
## macOS
Use our Makefile or directly:
```
brew install sdl3
c++ `sdl3-config --cflags` -I .. -I ../.. -I ../../backends
main.cpp ../../backends/imgui_impl_sdl3.cpp ../../backends/imgui_impl_opengl3.cpp ../../imgui*.cpp
`sdl3-config --libs` -framework OpenGl -framework CoreFoundation
```
## Emscripten
As of 2023-05-30 Emscripten doesn't support SDL3 yet.
