lerpTo
Will smoothly move the Camera at the selected target coordinated. The Camera will follow a target with a smooth linear interpolation, based on a lerp amount. lerp should be in range of 0 (slowest) to 1 (fastest). The lower that interpolation amount, the smoother - and thus slower - the following motion.
x and y are optional offsets in world units that will modify the final camera position. Offsets are added as-is and are not interpolated.
Note that Camera.update should be called in order to update to the new position. moveTo can be used to set the initial position while honoring the same x and y offset.
