Small elements are hard to touch precisely on mobile devices in cases like scatter charts with small bubbles. ### After: How is it fixed in this PR? Touch position in increased by "pointer size" (default value is 44px) so that elements are easier to be touched. ## Misc <!-- ADD RELATED ISSUE ID WHEN APPLICABLE --> - [x] The API has been changed (apache/echarts-doc#xxx). - [x] This PR depends on ZRender changes (ecomfe/zrender#918). ### Related test cases or examples to use the new APIs - test/target-size.html ### API Changes ```ts echarts.init(dom, null, { useCoarsePointer: 'auto', pointerDiameter: 44, ... }); ``` - `useCoarsePointer` (`'auto'` | `true` | `false`): whether to enable thie feature. If set to be `'auto'`, it's turned on only for mobile devices. - `pointerDiameter` (`number`): touch position is increased by this pointer size in diameter.
