| * ---------------------------------------------------------- |
| * [STRATEGY_MERGE] Merge properties or erase all properties: |
| * |
| * Based on the fact that the existing zr element probably is reused, we now consider whether |
| * merge or erase all properties to the existing elements. |
| * That is, if a certain props is not specified in the latest return of `renderItem`: |
| * + "Merge" means that do not modify the value on the existing element. |
| * + "Erase all" means that use a default value to the existing element. |
| * |
| * "Merge" might bring some unexpected state retaining for users and "erase all" seems to be |
| * more safe. "erase all" forces users to specify all of the props each time, which is recommended |
| * in most cases. |
| * But "erase all" theoretically disables the chance of performance optimization (e.g., just |
| * generete shape and style at the first time rather than always do that). |
| * So we still use "merge" rather than "erase all". If users need "erase all", they can |
| * simply always set all of the props each time. |
| * Some "object-like" config like `textConfig`, `textContent`, `style` which are not needed for |
| * every element, so we replace them only when users specify them. And that is a total replace. |
| * |
| * TODO: There is no hint of 'isFirst' to users. So the performance enhancement cannot be |
| * performed yet. Consider the case: |
| * (1) setOption to "mergeChildren" with a smaller children count |
| * (2) Use dataZoom to make an item disappear. |
| * (3) User dataZoom to make the item display again. At that time, renderItem need to return the |
| * full option rather than partial option to recreate the element. |
| * |
| * ---------------------------------------------- |
| * [STRATEGY_NULL] `hasOwnProperty` or `== null`: |
| * |
| * Ditinguishing "own property" probably bring little trouble to user when make el options. |
| * So we trade a {xx: null} or {xx: undefined} as "not specified" if possible rather than |
| * "set them to null/undefined". In most cases, props can not be cleared. Some typicall |
| * clearable props like `style`/`textConfig`/`textContent` we enable `false` to means |
| * "clear". In some other special cases that the prop is able to set as null/undefined, |
| * but not suitable to use `false`, `hasOwnProperty` is checked. |
| * |
| * --------------------------------------------- |
| * [STRATEGY_TRANSITION] The rule of transition: |
| * + For props on the root level of a element: |
| * If there is no `transition` specified, tansform props will be transitioned by default, |
| * which is the same as the previous setting in echarts4 and suitable for the scenario |
| * of dataZoom change. |
| * If `transition` specified, only the specified props will be transitioned. |
| * + For props in `shape` and `style`: |
| * Only props specified in `transition` will be transitioned. |
| * + Break: |
| * Since ec5, do not make transition to shape by default, because it might result in |
| * performance issue (especially `points` of polygon) and do not necessary in most cases. |
| * |
| * @return if `isMorphTo`, return `allPropsFinal`. |
