Particle position incorrect for first rendered frame when camera is panned away from world origin

[trixiegoff]

Particles emitted while the camera is panned away from the world origin, and where the emitter would be outside the visible area if the camera were at world origin, are displayed for their first frame in an incorrect location. After the first rendered frame of the particle's existance, the position is correct, resulting in a brief flash in the incorrect position.

This appears to be because of the following in the reset function setting sprite.position.x/y, which I believe are the display coordinates, to be the passed world coordinates:

Phaser.Sprite.prototype.reset = function(x, y) {
    this.x = x;
    this.y = y;
    this.position.x = x;
    this.position.y = y;

Upon replacing:

    this.position.x = x;
    this.position.y = y;

with:

    this.position.x = this.x - (this.game.world.camera.x * this.scrollFactor.x);
    this.position.y = this.y - (this.game.world.camera.y * this.scrollFactor.y);

the behavior ceases to occur.

While I assume that this issue can occur with any other sprite, I've been unable to replicate it outside of the particle emitter.
