I'm not catch you here.
We have already changed pixels to points above
`this->setContentSize(CC_SIZE_PIXELS_TO_POINTS(Size(_layerSize.width * _mapTileSize.width, _layerSize.height * _mapTileSize.height)));`
Why we need setScale for layer?
and base on your sample which you write at 4558 issue:
`canvas 960*640
designresoutionsize 960*640`
Isn't this `_contentScaleFactor` value equal to 1.0f, which is the default value?
And I test it with different design resolution size, make scale factor to 1.0f and 2.0f, it seems ok for me. But if I set scale for layer use _contentScaleFactor, it seems too large when scale factor set to 2.0f...
Am I missing something here? please tell me if so, thanks.
