The Canvas Renderer and WebGL Multi Pipeline now uses the new renderRoundPixels boolean to determine if it can render a Sprite or a Texture with rounded position values, or not. This fixes an issue where black lines would appear between tightly grouped sprites or tiles at non-integer Camera zoom values. Fix #6907
