-Extra fonts for ImGui.
+---------------------------------
-THOSE FONTS ARE OPTIONAL.
+ EXTRA FONTS FOR IMGUI
+---------------------------------
 
-ImGui embeds a copy of 'proggy_clean' that you can use without any external files.
+ImGui embeds a copy of 'ProggyClean.ttf' that you can use without any external files.
-Export your own font with bmfont (www.angelcode.com/products/bmfont).
 
-bmfont reads fonts (.ttf, .fon, etc.) and output a .fnt file and a texture file, e.g:
+Load .TTF file with:
 
-  proggy_clean.fon --> [bmfont] ---> proggy_clean_13.fnt
+  ImGuiIO& io = ImGui::GetIO();
-                                     proggy_clean_13.png
+  io.Font = new ImFont();
+  io.Font->LoadFromFileTTF("myfontfile.ttf", size_pixels);
   
-If you need a free font that supports chinese/japanese characters, you can use the M+ fonts.
+Add a third parameter to bake specific font ranges:
-TTF and sources are availables at http://mplus-fonts.sourceforge.jp/mplus-outline-fonts.
-This directory include some of the M+ fonts converted by bmfont.

+  io.Font->LoadFromFileTTF("myfontfile.ttf", size_pixels, ImFont::GetGlyphRangesDefault());		// Basic Latin, Extended Latin 
+  io.Font->LoadFromFileTTF("myfontfile.ttf", size_pixels, ImFont::GetGlyphRangesJapanese());		// Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs

-Configure bmfont:
+Offset font by altering the io.Font->DisplayOffset value:
 
-  - Export .fnt as Binary
+  io.Font->DisplayOffset.y += 1;   // Render 1 pixel down
-  - Output .png, 32-bits (or whatever is suitable for your loader/renderer)
-  - Tip: uncheck "Render from TrueType outline" and "Font Smoothing" for best result with non-anti-aliased type fonts. 
-    But you can experiment with other settings if you want anti-aliased fonts.
-  - Tip: use pngout.exe (http://advsys.net/ken/utils.htm) to further reduce the file size of .png files
-    All files in this folder have been optimised with pngout.exe

+-----------------------------------
+ RECOMMENDED SIZES
+-----------------------------------
 
-(A) Use font data embedded in ImGui
+	ProggyTiny.ttf			Size: 10.0f			Offset: Y: +1
+	ProggyClean.ttf			Size: 13.0f			Offset: Y: +1
 	
-    // Access embedded font data
-    const void* fnt_data;   // pointer to FNT data
-    unsigned fnt_size;      // size of FNT data
-    const void* png_data;   // pointer to PNG data
-    unsigned int png_size;  // size of PNG data
-    ImGui::GetDefaultFontData(&fnt_data, &fnt_size, &png_data, &png_size);
-
-  1. Load the .FNT data from 'fnt_data' (NB: this is done for you by default if you don't do anything)
-
-    ImGuiIO& io = ImGui::GetIO();
-    io.Font = new ImFont();
-    io.Font->LoadFromMemory(fnt_data, fnt_size);
-    
-  2. Load the .PNG data from 'png_data' into a texture
-
-//-----------------------------------------------------------------------------
-
-(B) Use fonts from external files
-
-  You need to set io.Font->TexUvForWhite to UV coordinates pointing to a white pixel in the texture.
-  You can either locate a white pixel manually or use code at runtime to find or write one.
-  The OpenGL example include sample code to find a white pixel given an uncompressed 32-bits texture:
-
-  	  // Automatically find white pixel from the texture we just loaded
-	  // (io.Font->TexUvForWhite needs to contains UV coordinates pointing to a white pixel in order to render solid objects)
-	  for (int tex_data_off = 0; tex_data_off < tex_x*tex_y; tex_data_off++)
-	      if (((unsigned int*)tex_data)[tex_data_off] == 0xffffffff)
-	      {
-	          io.Font->TexUvForWhite = ImVec2((float)(tex_data_off % tex_x)/(tex_x), (float)(tex_data_off / tex_x)/(tex_y));
-	          break;
-	      }
-
-  1. Load the .FNT data, e.g.
-
-    ImGuiIO& io = ImGui::GetIO();
-    
-    // proggy_clean_13 [default]
-    io.Font = new ImFont();
-    io.Font->LoadFromFile("proggy_clean_13.fnt");
-    IM_ASSERT(io.Font->IsLoaded());
-    io.Font->TexUvForWhite = ImVec2(0.0f/256.0f,0.0f/128);
-    io.Font->DisplayOffset = ImVec2(0.0f, +1.0f);
-
-    // proggy_small_12
-    io.Font = new ImFont();
-    io.Font->LoadFromFile("proggy_small_12.fnt");
-    IM_ASSERT(io.Font->IsLoaded());
-    io.Font->TexUvForWhite = ImVec2(84.0f/256.0f,20.0f/64);
-    io.Font->DisplayOffset = ImVec2(0.0f, +2.0f);
-    
-    // proggy_small_14
-    io.Font = new ImFont();
-    io.Font->LoadFromFile("proggy_small_14.fnt");
-    IM_ASSERT(io.Font->IsLoaded());
-    io.Font->TexUvForWhite = ImVec2(84.0f/256.0f,20.0f/64);
-    io.Font->DisplayOffset = ImVec2(0.0f, +3.0f);
-    
-    // courier_new_16
-    io.Font->LoadFromFile("courier_new_16.fnt");
-    io.Font->TexUvForWhite = ImVec2(1.0f/256.0f,4.0f/128);
-    
-    // courier_new_18
-    io.Font->LoadFromFile("courier_new_18.fnt");
-    io.Font->TexUvForWhite = ImVec2(4.0f/256.0f,5.0f/256);
-
-
-  2. Load the matching .PNG data into a texture
