use 2d camera instead of 3d one

[adsick]

I'm not sure why this crate uses 3d camera, the content is all 2d. Camera 2d has OrthographicProjection component which has scale, it is what you want instead of adjusting z coordinate (unless you actually want images to float in 3d space)

useful: bevyengine/bevy#2580

P.S. beware of this issue: bevyengine/bevy#239

Will 2d has better performance?

[adsick]

It may not perform better, but it makes more sense, and (hopefully) is simpler to work with.

float in 3d space

I just tried modify the camera to iso view when I known it's 3d camera. Image can have different coordinates and it looks interesting .

for me, 3d is more familiar, :)

change to use ortho camera, the distortion should be fixed now.
