1. It works well. Thank you, Andreas.
Maybe only some glitch, when we resize a column narrow enough (see pic).
2. I managed *.sln to be opened in VS 2010, changing two upper lines:
Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio Express 2012 for Windows Desktop
Microsoft Visual Studio Solution File, Format Version 11.00
# Visual Studio Express 2010 for Windows Desktop
And set "Property Pages" - "VC++ Directories" - "Platform Toolset" to "v100", to find all include files.
3. Now I can think how to make letters look outstanding. (In my future epic programs).
With some coloring and shading of edges, probably.
I thought of some tags to change colors inline, like <#RRGGBB> or <#RRGGBBAA>, but likely it's better not to make things complex and let the program make separate calls for different colors.
