Discussion Points (already discussed @ svgwg f2f june 2015)

1. Better revision target: CSS transforms level 1 or 2?
   • Already revised for level 1
   • Easy to revise also for level 2 ( draft ) -> better
2. How is "vector effect" handled in 3d context?
   • Any usecases?
   • Any side effects?
   • -> For the moment, vector effect should be focused on 2D.

Notes

I (stakagi) have noticed that there is CSS Transforms Level 2 after making this document. Since scale is mentioned by its issue, these revision may be good to be applied to Level 2. So, I made a revised draft.

I think that scale2D should be related to css-device-adapt.
