Loading/Transition Screen fading
 |  |
As with the loading screen used in Portal 2, P2:CE's loading screen is layouted with overlayed images that are fading in/out based on the loading progress. Additionally, P2:CE differentiates between loading into a map from the main menu and transitioning into a map from a previous map.
The loading screen of P2:CE supports two images with a fade happening at 50%. To fade between two images, an index will be added to the asset path.
Example
With this, the loading screen will fade between [ADDON PATH]/.assets/loading_screen_1.png and [ADDON PATH]/.assets/loading_screen_2.png. If only one background image is wanted with no fade between images, just having [ADDON PATH]/.assets/loading_screen_1.png available will suffice.
