Text angle control

[tomczak]

This is a trifle, but I'll mention it: I spent quite a while today trying to find the control arrow in the Text angle compass Control (my fault - I haven't used it for a while). Maybe making it a bit bolder or painting it in red or some other colour would make it easier to spot?

I made the arrow bolder so it stands out better from the rest of the control.
