Not an implementer, but... 0.1px isn't very small if it's a CSS 96th of an inch and you're working with a 4800dpi printer. Similarly 0.1 degree is larger than it might sound - the human eye can easily see if a rectangle is rotated by 0.1 pixel, it's got built-in hardware for it :) Of course, an implementation could support higher resolution. The groff text formatter used (may still use) millipoints internally. So the 0.1px is probably OK, since implementors will likely realise they need more if they do :-), but 0.1 degrees still seems too coarse a granularity to me.
