Ah. I see. So it seems that if a person is familiar with the backwards way that SVG specifies linear angles (if that's what it does, or is it just for rotating, etc.?), then that person might reasonably expect CSS to behave in a similar way, even though it goes against everything else he would expect from a lifetime of seeing diagrams of angles and tools for measuring angles in the opposite direction. Or is it just rotate() and skew() in SVG? Because frankly, if so, then I don't have any problem at all with linear directions following the protactor convention, and transforms following the SVG convention. If someone wants to match a gradient to a rotated object, they can easily add a minus sign. Brendan has indicated that there are bloggers out there commenting on the current transform implementations as being buggy or wrong for going clockwise with it's degrees. Just wait until we are all asked to flip our protractors over and read the numbers backwards in order to specify direction! It is completely unintuitive to the average person, for whom 90 degrees is up. We could go with compass directions, I suppose, but it would be harder to be precise. NE is 45deg (for ordinary people, I mean) and NNE is 67.5deg, but I wouldn't know how to specify something in between that way.
