* 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() or
* 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.
