This class is a simple subclass of MotionPath for defining
two keyframes to hold the valueFrom, valueTo, and
valueBy properties.
The MotionPath class itself can define any number of keyframes.

valueBy:Object| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 4 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
Optional property which specifies the delta used to calculate
either the valueFrom or valueTo value.
Providing this optional property lets the effect
calculate the necessary from/to values if either
are not provided or are to be determined dynamically when the animation
begins.
The way that the valueBy value is used depends on which of the
other values are set. If neither are set, then the valueFrom
value is determined from the current property value in the target,
and the valueTo value is valueFrom + valueBy.
If one or the other is set, but not both, then
the unset value is calculated by the other value:
valueTo = valueFrom + valueBy or
valueFrom = valueTo - valueBy). If both are set, then the
valueBy property is ignored.
Note that since valueBy is of type
Object, the effect cannot directly calculate the other values
from it. It uses the effect's interpolator
to calculate the values by calling the interpolator's increment()
and decrement() methods.
If no interpolator is set, then it will use NumberInterpolator by default.

The starting value for the property during the animation.
A value of Null or NaN (in the case of Numbers) specifies that a
value must be determined dynamically at runtime, either by
getting the value from the target property directly or calculating
it if the other value is valid and there is also a valid
valueBy value supplied.

Constructor. You can specify both the
valueFrom and valueTo parameters,
or specify the valueBy parameter and either the valueFrom
or valueTo parameter.
If you omit these parameters, Flex calculates them from the effect target.
