I'm setting the video to 800, 600 flex-width, scale auto, yet the title screen seems to render off to the left. How can I center the title screen?

During gameplay, the display fits the entire viewport nicely:

But the title is off to the left:

I understand this is due to the loaded background image of the title screen, but at centering it on the black background would look nicer.

Game.js: video loader:

if (!me.video.init(800, 600, {
wrapper : "screen",
renderer : me.video.CANVAS,
scale : "auto",
scaleMethod : "flex-width",
doubleBuffering : true,
transparent : true,
antiAlias : true
})) {
alert("Your browser does not support HTML5 canvas.");
return;
}

Title.js (Title screen):

me.game.world.addChild(new (me.Renderable.extend ({
// constructor
init : function() {

this._super(me.Renderable, 'init', [0, 0, me.game.viewport.width, me.game.viewport.height]);

Your title screen renderable is positioning itself in the upper left corner of the screen (0,0), with the same size as the screen. You'll have to apply centering logic on the renderable position:

this._super(me.Renderable, 'init', [
  (me.game.viewport.width - 800) / 2,
  (me.game.viewport.height - 600) / 2,
  800,
  600
]);

The title screen is still rendered to the far left side of the screen.

Are you adjusting the position anywhere else?
