Enhancement: Path that doesn't automatically call closePath(); about libcanvas HOT 5 CLOSED

But we must close that path, because it can be mistakly continued by next element. But you always can create your own behavior own using processPath. Something like that:

renderTo: function (ctx) {
    // we should set "true" as second parameter, if we want no wrap
    this.path.processPath( ctx, true );
    // path is not closed, we can continue it
    ctx.lineTo(500, 500);
    ctx.closePath();
    ctx.fill( 'red' );
}

Do you like that way?

Why do you say 'must'? Do you suggest mistake by user, not closing paths properly and getting unexpected results, or some kind of inconsistencies across browsers? As far as I know not closing path works perfectly, across different browsers, and provides me what I need. Just to give you an example, I'm rendering a racing track, consisting of 3 different sectors, each in different color. Have a look here (track picture) http://liveracers.com/#/Views/LiveTiming/Simracing.cz/SR5%20-%20Mini,%20sk.%201 . That's what I need to replicate.

I mean first - "mistake by user".
If we are using createShaper - we can't control closing path & we dont know, who will be really use it next time.
Shaper was created for easy and inside (without interactions with other objects) vector operations and I recommend to create your own drawable object (maybe, based on Shaper) if you want some specific behavior.
Unfortunately, I cant watch your game based on Silverlite, because I am using Linux. Can you send me an screenshot?

There are many ways how to mess up your code, I think this would be a nice feature. Anyways I've done it by inheriting from path:

var Sector = atom.Class(
/** @Lends {LibCanvas.Shapes.Path.prototype} */
{
Extends: LibCanvas.Shapes.Path,
processPath: function (ctx, noWrap) {
if (!noWrap) ctx.beginPath();
this.each(function (method, args) {
ctx[method].apply(ctx, args);
});
return ctx;
}
});

and replacing

path = path.snapToPixel().build();

with

path = new Sector(path.snapToPixel());

works fine

this is what I'm after:

there are 4 paths - green (not closed), red (not closed), blue (not closed) and gray(closed)

Well, it is nice solution of the task =)
