If so, dirty will only trigger the render2d refresh hover layer

Render2D instance will be assigned when element is associated with render2d

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. }

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 ignoreNever increase to target size
For increamental rendering
Will use this to calculate transform matrix instead of Element itseelf if it's give. Not exposed to developers
