/**
 * Avoid holes or border artifacts between tiles.
 * Sometimes the scale by 1.01 trick doesn't work, a greater value should be used. This method finds the correct value for you.
 * If you use openfl_legacy, pack your atlas using reduceBorderArtifact option in TexturePacker. There is no need to use this option on openfl_next.
 * You should update the scale of your tiles if your resize the screen during the game to always have the best scale value.
