v13.0.0

added

• Event: also provide a reference to the camera viewport being resized when emitting VIEWPORT_ONRESIZE
• Unit Test: added base64 encoded data preload testing for image and audio assets
• Utils: new isDataUrl() helper returning true if the given url is in the data:[<mediatype>][;base64],<data> format.

Changed

• Core: full ES6 refactoring of me.device, and API clean-up (@see https://github.com/melonjs/melonJS/wiki/Upgrade-Guide#120x-to-130x-stable)
• Game: refactoring of the global game into an instantiable Application object, with game now being the default instance of it (@see #1091)
• Loader: onload and onerror callbacks are now optionals when directly loading assets (easier with base64 encoded assets)
• Physic: World physic implementation is now properly tight to its corresponding parent application/game (@see #1091)
• Physic: Gravity is now properly applied as a force, instead of directly modifying a body velocity
• Physic: Gravity now properly takes in account the body mass
• Physic: resulting force is now properly cancelled at the end of an update cycle (not required anymore to manually set it to 0 in user code)

Fixed

• Doc: fix missing Timer documentation following previous refactoring
• Loader: fix loading/preloading of base64 audio assets, and base64 encoded FontFace
• Renderer: fix a regression with the masking features in the Canvas Rendering mode
• Text: fix an uncaught exception when removing Text object from the game world that use offScreenCanvas texture caching (thanks @wpernath)
