I released this into tuhopuu2 and then 2 different patchs for
bf-blender, for some resion it got removed (because it didnt use the
text theme colour???)
anyhow- it forfills all the requirements ton and others set, so I hope
this is acceptable, its usefull for architectual stuff, and its not
intrusive (selected verts only display info- not all by default as it was)
- merry xmas all :)
