Orthographic Camera API 3.4.0

BREAKING CHANGE: The camera.go now uses a standard Defold camera component
CHANGE: The camera.set_dpi_ratio() function has been deprecated. The camera will use window.get_display_scale() instead.

Migration guide:

• The projection field has been removed
  • FIXED_AUTO - Check Automatic zoom
  • FIXED_ZOOM - Set the Zoom property to desired zoom
