Hi WebKit,

I would like to ask if there are objections to implement the canvas Path object.

The HTML Canvas specification and the WHAT WG HTML specification define the 
Path object [1][2]. The Path object and the CanvasRenderingContext2D share some 
graphics operations[3]: 

- closePath
- lineTo
- moveTo
- arc
- arcTo
- ellipse (not implemented yet)
- quadraticCurveTo
- cubicCurveTo
- rect

But instead of drawing onto a Canvas, the operations get applied to a Path 
object. Furthermore the object allows adding other Paths with transforms. A 
Path object can then be drawn onto a Canvas.

I opened https://bugs.webkit.org/show_bug.cgi?id=97333 for a patch and detailed 
discussions.

Greetings,
Dirk
