+
+ 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 default font with:
+
+   ImGuiIO& io = ImGui::GetIO();
+   io.Fonts->AddFontDefault();
+
+ Load .TTF file with:
+
+   ImGuiIO& io = ImGui::GetIO();
+   io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+  
+ Detailed options:
+
+   ImFontConfig config;
+   config.OversampleH = 3;
+   config.OversampleV = 3;
+   config.GlyphExtraSpacing.x = 1.0f;
+   io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
+
+ Combine two fonts into one:
+
+   // Load main font
+   io.Fonts->AddFontDefault();
+
+   // Add character ranges and merge into main font
+   ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
+   ImFontConfig config;
+   config.MergeMode = true;
+   io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges);
+   io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config, io.Fonts->GetGlyphRangesJapanese());
+
+ Add a fourth parameter to bake specific font ranges only:
+
+   // Basic Latin, Extended Latin
+   io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesDefault());
+   
+   // Include full set of about 21000 CJK Unified Ideographs
+   io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesJapanese());
+   
+   // Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
+   io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, NULL, io.Fonts->GetGlyphRangesChinese());
+
+ Offset font vertically by altering the io.Font->DisplayOffset value:
+
+   ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
+   font->DisplayOffset.y += 1;   // Render 1 pixel down
+
+---------------------------------
+ EMBED A FONT IN SOURCE CODE
+---------------------------------
+
+ 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, ...);
+   
+ Or 
+ 
+   ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);

+// ImGui - binary_to_compressed_c.cpp
+// Helper tool to turn a file into a C array.
+// The data is first compressed with stb_compress() to reduce source code size.
+// Then encoded in Base85 to fit in a string so we can fit roughly 4 bytes of compressed data into 5 bytes of source code (suggested by @mmalex)
+// (If we used 32-bits constants it would require take 11 bytes of source code to encode 4 bytes.)
+// Useful if you want to embed fonts into your code.
