Ya that does fix the issue... but in the real world, the game view will always be scaled, will it not? We need to adjust to devices from 800x400 to 4k monitors, all using Pixel Art...
With PixelPerfect, you can set pixel "zoom level", so we'd simply detect screen size at startup, and assign a zoom level to the camera that will give nice results on that size screen.
With tk2d, I don't see any way to make a dynamic sized camera, that always gives us whole pixels. Overrides seem device specific which is not ideal.
