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.

+Instructions to rebuild imgui_impl_sdlgpu3_shaders.h
+(You don't need to copy this folder if you are using the backend as-is)
+
+1) Compile the raw shader files to SPIRV:
+
+    glslc -o vertex.spv -c shader.vert
+    glslc -o fragment.spv -c shader.frag
+
+
+2) Build SDL_shadercross (https://github.com/libsdl-org/SDL_shadercross)
+
+
+3-A) Compiling for the Vulkan Driver:
+
+    Nothing to do, you just need the previous vertex.spv/fragment.spv, proceed to step 4
+
+
+3-B) Compiling for the DirectX 12 Driver:
+
+    ./shadercross vertex.spv -s SPIRV -d DXBC -t vertex -e main -o vertex.dxbc
+    ./shadercross fragment.spv -s SPIRV -d DXBC -t fragment -e main -o fragment.dxbc
+
+    Proceed to step 4
+
+
+3-C) Compiling for Metal (On windows you'll need the Metal Developer Tools for Windows, on linux you might use wine, but I never tested it):
+
+    ./shadercross vertex.spv -s SPIRV -d MSL -t vertex -e main -o vertex.metal
+    ./shadercross fragment.spv -s SPIRV -d MSL -t fragment -e main -o fragment.metal
+
+    xcrun -sdk macosx metal -o vertex.ir -c vertex.metal
+    xcrun -sdk macosx metal -o fragment.ir -c fragment.metal
+    xcrun -sdk macosx metallib -o vertex.metallib -c vertex.ir
+    xcrun -sdk macosx metallib -o fragment.metallib -c fragment.ir
+
+    note: use .metal outputs for updating msl_vertex / msl_fragment variables, and use .metallib outputs for metallib_vertex / metallib_fragment variables
+
+    Proceed to step 4
+
+
+4) Use a tool like https://notisrac.github.io/FileToCArray/ or misc/fonts/binary_to_compressed_c.cpp in imgui repository to convert the file to a uint8_t array.
