 The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' that you can use without any external files.
 Those are only provided as a convenience, you can load your own .TTF files.

 LOADING INSTRUCTIONS
---------------------------------

 Load .TTF file with:

   ImGuiIO& io = ImGui::GetIO();
   io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_pixels);
  
 Add a third parameter to bake specific font ranges:

   io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, io.Fonts->GetGlyphRangesDefault());   // Basic Latin, Extended Latin 
   io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, io.Fonts->GetGlyphRangesJapanese());  // Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
   io.Fonts->LoadFromFileTTF("myfontfile.ttf", size_pixels, io.Fonts->GetGlyphRangesChinese());   // Include full set of about 21000 CJK Unified Ideographs

 Offset font vertically by altering the io.Font->DisplayOffset value:

   ImFont* font = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_pixels);
   font->DisplayOffset.y += 1;   // Render 1 pixel down

 If you want to embed the font in source code (e.g. in your engine, so it doesn't have file-system dependencies);
 Compile and use 'binary_to_compressed_c.cpp' to create a compressed C style array. Then load the font with:
 
   ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
