Optional opts: GroupPropsProtected _$eventIf element is used as a component of other element.
If element has been moved to the hover layer.
If so, dirty will only trigger the render2d refresh hover layer
If element was painted on the screen
Render2D instance will be assigned when element is associated with render2d
Protected _normalWill translated the element to the anchor position before applying other transforms.
Id for mapping animation
The string value of textPosition needs to be calculated to a real postion.
For example, 'inside' is calculated to [rect.width/2, rect.height/2]
by default. See contain/text.js#calculateTextPosition for more details.
But some coutom shapes like "pin", "flag" have center that is not exactly
[width/2, height/2]. So we provide this hook to customize the calculation
for those shapes. It will be called if the style.textPosition is a string.
Prepared out object. If not provided, this method should be responsible for creating one.
{x, y, width, height}
out The same as the input out. { x: number. mandatory. y: number. mandatory. align: string. optional. use style.textAlign by default. verticalAlign: string. optional. use style.textVerticalAlign by default. }
Optional currentWhether it can be dragged.
Whether is it dragging.
Scale ratio
If ignore drawing and events of the element object
If ignore clip from it's parent or hosts. Applied on itself and all it's children.
NOTE: It won't affect the clipPath set on the children.

Optional prevWhether to respond to mouse events.
Optional stateProxy function for getting state with given stateName. Render2D will first try to get with stateProxy. Then find from states if stateProxy returns nothing
targetStates will be given in useStates

targetStates will be given in useStates
Optional targetStates: string[]Animation config applied on state switching.
Store of element state. 'normal' key is preserved for default properties.
Optional textConfig of textContent. Inlcuding layout, color, ...etc.
Optional textConfig for guide line calculating.

动画
Optional key: stringOptional loop: booleanWhether to loop animation.
Optional allowDiscreteAnimation: booleanWhether to allow discrete animation @example: el.animate('style', false) .when(1000, {x: 10} ) .done(function(){ // Animation done }) .start()
Animate from the target state to current state.
The params and the value are the same as this.animateTo.
Optional animationProps: MapToType<GroupProps, boolean>Optional cfg: ElementAnimateConfigOptional animationProps: MapToType<GroupProps, boolean>A map to specify which property to animate. If not specified, will animate all.
// Animate position
el.animateTo({
position: [10, 10]
}, { done: () => { // done } })
// Animate shape, style and position in 100ms, delayed 100ms, with cubicOut easing
el.animateTo({
