Matter.TileBody.setFromTileCollision no longer checks if the shape is concave or convex before modifying the vertices, as the update to the Matter.js lib in 3.12 stopped this from working with Tiled collision shapes.

* `WebGLRenderer.preRender` now calls `gl.clearColor` in order to restore the background clear color in case something, like a Render Texture, has changed it.
* `Map.set` will now update an existing value if you provide it with a key that already exists within the Map. Previously, if you tried to set the value of a key that existed it would be skipped.
* `MatterSprite` would set its `type` property to be `Image`. It now sets it to be `Sprite` as it should do.
