Use_2D_Pixel_Snap doesn't Work on Non-Uniformly Resized Game Window

[ScotFlux]

I'm not sure if this is Jetpaca bug or Godot's.

• Any OS (I guess) ?
• Godot 2.1beta

=> Happened : When we resized game window non-uniformly (width and height ratio un-keeped), use_2d_pixel_snap didn't work. It worked when width and height ratio keeped.

=> Expected : I guess "use_2d_pixel_snap" should work even if width and/or height of the game window resized.
