Hi Joost,

I would prefer the curved border to be drawn, up to half the available 
height/width (so in effect the border would look a bit pointy halfway 
the box; probably people will put this effect to good use :)!). 
Alternatively, if the radius doesn’t fit, it could be adjusted to the 
largest value that does.

This would look a lot better for cases where the radius is specified in 
pixels, but the height is determined by e.g. the content height (it 
might occasionally only contain 1 line) or em units (the user may have 
selected smaller fonts than the designer), etc.

Having one box with square corners on a page filled with boxes all 
having rounded corners would look pretty bad.
