I was thinking of upwards rightwards. I fully agree it is ugly, but I like  
ugly better than ambiguous. As a candidate for something that's neither,  
what do you think of Fantasai's proposal of "<point> to <point>", which  
would give "bottom to right". Or just going back at "from <point>", which  
would give "from bottom left".

True.

I'd need to think about that, but while I am not immediately convinced I  
like this, it fits the non-ambiguous criteria as well as the  
non-awkward-wording criteria, so maybe that could work.

In addition to clockwise, the WG also settled on 0 being north/up, so  
45deg would point up-and-to-the-right.
