The uniform entry of set text style, that is, retrieve style definitions from `model` and set to `textStyle` object. Never in merge mode, but in overwrite mode, that is, all of the text style properties will be set. (Consider the states of normal and emphasis and default value can be adopted, merge would make the logic too complicated to manage.) The `textStyle` object can either be a plain object or an instance of `zrender/src/graphic/Style`, and either be the style of normal or emphasis. After this mothod called, the `textStyle` object can then be used in `el.setStyle(textStyle)` or `el.hoverStyle = textStyle`. Default value will be adopted and `insideRollbackOpt` will be created. See `applyDefaultTextStyle` `rollbackDefaultTextStyle` for more details. opt: { disableBox: boolean, Whether diable drawing box of block (outer most). isRectText: boolean, autoColor: string, specify a color when color is 'auto', for textFill, textStroke, textBackgroundColor, and textBorderColor. If autoColor specified, it is used as default textFill. useInsideStyle: `true`: Use inside style (textFill, textStroke, textStrokeWidth) if `textFill` is not specified. `false`: Do not use inside style. `null/undefined`: use inside style if `isRectText` is true and `textFill` is not specified and textPosition contains `'inside'`. forceRich: boolean }

Give some default value to the input `textStyle` object, based on the current settings in this `textStyle` object. The Scenario: when text position is `inside` and `textFill` is not specified, we show text border by default for better view. But it should be considered that text position might be changed when hovering or being emphasis, where the `insideRollback` is used to restore the style. Usage (& NOTICE): When a style object (eithor plain object or instance of `zrender/src/graphic/Style`) is about to be modified on its text related properties, `rollbackDefaultTextStyle` should be called before the modification and `applyDefaultTextStyle` should be called after that. (For the case that all of the text related properties is reset, like `setTextStyleCommon` does, `rollbackDefaultTextStyle` is not needed to be called).
