The proposal reflects the work done on the prototype to get a better understanding of the various issues involved when using fragment and vertex shaders for custom effects. It also reflects on the feedback and suggestions of several people, in particular the co-editors for the proposal, Dean Jackson and Erik Dahlström.

As Vincent mentioned, we support this proposal. It brings a lot of power, and reflects the way graphics architecture has been heading for the last decade. 

Our main concern is security, which is very similar to the issues with WebGL. The WebGL group at Khronos have been working with GPU vendors to improve this situation and hopefully we'll soon be comfortable allowing arbitrary Web content the ability to run WebGL/shaders.

Anyway, the bottom line is that we think that CSS shaders is a great proposal, and we were very happy to work with Vincent and Adobe on this.
