// Dear ImGui: standalone example application for SDL2 + SDL_Renderer
// (SDL is a cross-platform general purpose library for handling windows, inputs,
// OpenGL/Vulkan/Metal graphics context creation, etc.)
//
// TODO: consider switching to the below
// Important to understand: SDL_Renderer is an _optional_ component of SDL2.
// For a multi-platform app consider using e.g. SDL+DirectX on Windows and
// SDL+OpenGL on Linux/OSX.

// - If no fonts are loaded, dear imgui will use the default font. You can

// them.
// - AddFontFromFileTTF() will return the ImFont* so you can store it if you
// need to select the font among multiple.
// - If the file cannot be loaded, the function will return a nullptr. Please
// handle those errors in your application (e.g. use an assertion, or display
// an error and quit).
// - The fonts will be rasterized at a given size (w/ oversampling) and stored
// into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(),
// which ImGui_ImplXXXX_NewFrame below will call.
// - Use '#define IMGUI_ENABLE_FREETYPE' in your imconfig file to use Freetype
// for higher quality font rendering.
// - Read 'docs/FONTS.md' for more instructions and details.
// - Remember that in C/C++ if you want to include a backslash \ in a string
// literal you need to write a double backslash \\ !
