* Load Fonts
*
* - If no fonts are loaded, dear imgui will use the default
* font. You can also load multiple fonts and use
* ImGui::PushFont()/PopFont() to select 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 \\ !
* - Our Emscripten build process allows embedding fonts to be
* - accessible at runtime from the "fonts/" folder. See
* Makefile.emscripten for details.
* auto imguiIO = m_imgui.getIO();
* imguiIO.Fonts->AddFontDefault();
* imguiIO.Fonts->AddFontFromFileTTF("c:\\Windows\\Fonts\\segoeui.ttf", 18.0f);

* imguiIO.Fonts->AddFontFromFileTTF("../../misc/fonts/Roboto-Medium.ttf", 16.0f);
* imguiIO.Fonts->AddFontFromFileTTF("../../misc/fonts/Cousine-Regular.ttf", 15.0f);

* "c:\\Windows\\Fonts\\ArialUni.ttf", 18.0f, nullptr,
* io.Fonts->GetGlyphRangesJapanese()); IM_ASSERT(font != nullptr);
