+ *
+ * We originally consider to introduce new events like `pagemovemove` and `pagemouseup`
+ * to resolve this issue. But some drawbacks of it is described in
+ * https://github.com/ecomfe/zrender/pull/536#issuecomment-560286899
+ *
+ * Instead, we referenced the specifications:
+ * https://www.w3.org/TR/touch-events/#the-touchmove-event
+ * https://www.w3.org/TR/2014/WD-DOM-Level-3-Events-20140925/#event-type-mousemove
+ * where the the mousemove/touchmove can be continue to fire if the user began a drag
+ * operation and the pointer has left the boundary. (for the mouse event, browsers
+ * only do it on `document` and when the pointer has left the boundary of the browser.)
+ *
+ * So the default `HandlerProxy` supports this feature similarly: if it is in the dragging
+ * state (see `pointerCapture` in `HandlerProxy`), the `mousemove` and `mouseup` continue
+ * to fire until release the pointer. That is implemented by listen to those event on
+ * `document`.
+ * If we implement some other `HandlerProxy` only for touch device, that would be easier.
+ * The touch event support this feature by default.
+ *
+ * Note:
+ * There might be some cases that the mouse event can not be
+ * received on `document`. For example,
+ * (A) `useCapture` is not supported and some user defined event listeners on the ancestor
+ * of zr dom throw Error .
+ * (B) `useCapture` is not supported Some user defined event listeners on the ancestor of
+ * zr dom call `stopPropagation`.
+ * In these cases, the `mousemove` event might be keep triggered event
+ * if the mouse is released. We try to reduce the side-effect in those cases.
+ * That is, do nothing (especially, `findHover`) in those cases. See `isOutsideBoundary`.
+ *
+ * Note:
+ * If `HandlerProxy` listens to `document` with `useCapture`, `HandlerProxy` needs to
+ * make sure `stopPropagation` and `preventDefault` doing nothing if and only if the event
+ * target is not zrender dom. Becuase it is dangerous to enable users to call them in
+ * `document` capture phase to prevent the propagation to any listener of the webpage.
+ * But they are needed to work when the pointer inside the zrender dom.

+ * <A> This method MUST be called after all of the normal styles having been adopted
+ * to the `el`.
+ * <B> The input `hoverStyle` (that is, "emphasis style") MUST be the subset of the
+ * "normal style" having been set to the el.
+ * <C> `color` MUST be one of the "normal styles" (because color might be lifted as
+ * a default hover style).
+ *
+ * The reason: this method treat the current style of the `el` as the "normal style"
+ * and cache them when enter/update the "emphasis style". Consider the case: the `el`
+ * is in "emphasis" state and `setOption`/`dispatchAction` trigger the style updating
+ * logic, where the el should shift from the original emphasis style to the new
+ * "emphasis style" and should be able to "downplay" back to the new "normal style".
+ *
+ * Indeed, it is error-prone to make a interface has so many constraints, but I have
+ * not found a better solution yet to fit the backward compatibility, performance and
+ * the current programming style.
+ *
+ * (2)
+ * Call the method for a "root" element once. Do not call it for each descendants.
+ * If the descendants elemenets of a group has itself hover style different from the
+ * root group, we can simply mount the style on `el.hoverStyle` for them, but should
+ * not call this method for them.
+ *

+ * A final axis is translated and rotated from a "standard axis".
+ * So opt.position and opt.rotation is required.
+ *
+ * A standard axis is and axis from [0, 0] to [0, axisExtent[1]],
+ * for example: (0, 0) ------------> (0, 50)
+ *
+ * nameDirection or tickDirection or labelDirection is 1 means tick
+ * or label is below the standard axis, whereas is -1 means above
+ * the standard axis. labelOffset means offset between label and axis,
+ * which is useful when 'onZero', where axisLabel is in the grid and
+ * label in outside grid.
+ *
+ * Tips: like always,
+ * positive rotation represents anticlockwise, and negative rotation
+ * represents clockwise.
+ * The direction of position coordinate is the same as the direction
+ * of screen coordinate.
+ *
+ * Do not need to consider axis 'inverse', which is auto processed by
+ * axis extent.
+ *

+// ----------------------------------------------
+
+
+
+// ----------------
+// Charts (series)
+// ----------------
+
+
+
+// All of the series types, for example:
+// chart.setOption({
+//     series: [{
+//         type: 'line' // or 'bar', 'pie', ...
+//     }]
+// });
+
+// -------------------
+// Coordinate systems
+// -------------------
+
+
+
+// All of the axis modules have been included in the
+// coordinate system module below, do not need to
+// make extra import.
+
+// `cartesian` coordinate system. For some historical
+// reasons, it is named as grid, for example:
+// chart.setOption({
+//     grid: {...},
+//     xAxis: {...},
+//     yAxis: {...},
+//     series: [{...}]
+// });
+// `polar` coordinate system, for example:
+// chart.setOption({
+//     polar: {...},
+//     radiusAxis: {...},
+//     angleAxis: {...},
+//     series: [{
+//         coordinateSystem: 'polar'
+//     }]
+// });
+// `geo` coordinate system, for example:
+// chart.setOption({
+//     geo: {...},
+//     series: [{
+//         coordinateSystem: 'geo'
+//     }]
+// });
+// `singleAxis` coordinate system (notice, it is a coordinate system
+// with only one axis, work for chart like theme river), for example:
+// chart.setOption({
+//     singleAxis: {...}
+//     series: [{type: 'themeRiver', ...}]
+// });
+// `parallel` coordinate system, only work for parallel series, for example:
+// chart.setOption({
+//     parallel: {...},
+//     parallelAxis: [{...}, ...],
+//     series: [{
+//         type: 'parallel'
+//     }]
+// });
+// `calendar` coordinate system. for example,
+// chart.setOptionp({
+//     calendar: {...},
+//     series: [{
+//         coordinateSystem: 'calendar'
+//     }]
+// );
+// ------------------
+// Other components
+// ------------------
+
+
+
+// `graphic` component, for example:
+// chart.setOption({
+//     graphic: {...}
+// });
+// `toolbox` component, for example:
+// chart.setOption({
+//     toolbox: {...}
+// });
+// `tooltip` component, for example:
+// chart.setOption({
+//     tooltip: {...}
+// });
+// `axisPointer` component, for example:
+// chart.setOption({
+//     tooltip: {axisPointer: {...}, ...}
+// });
+// Or
+// chart.setOption({
+//     axisPointer: {...}
+// });
+// `brush` component, for example:
+// chart.setOption({
+//     brush: {...}
+// });
+// Or
+// chart.setOption({
+//     tooltip: {feature: {brush: {...}}
+// })
+// `title` component, for example:
+// chart.setOption({
+//     title: {...}
+// });
+// `timeline` component, for example:
+// chart.setOption({
+//     timeline: {...}
+// });
+// `markPoint` component, for example:
+// chart.setOption({
+//     series: [{markPoint: {...}}]
+// });
+// `markLine` component, for example:
+// chart.setOption({
+//     series: [{markLine: {...}}]
+// });
+// `markArea` component, for example:
+// chart.setOption({
+//     series: [{markArea: {...}}]
+// });
+// `legend` component scrollable, for example:
+// chart.setOption({
+//     legend: {type: 'scroll'}
+// });
+// `legend` component not scrollable. for example:
+// chart.setOption({
+//     legend: {...}
+// });
+// `dataZoom` component including both `dataZoomInside` and `dataZoomSlider`.
+// `dataZoom` component providing drag, pinch, wheel behaviors
+// inside coodinate system, for example:
+// chart.setOption({
+//     dataZoom: {type: 'inside'}
+// });
+// `dataZoom` component providing a slider bar, for example:
+// chart.setOption({
+//     dataZoom: {type: 'slider'}
+// });
+// `dataZoom` component including both `visualMapContinuous` and `visualMapPiecewise`.
+// `visualMap` component providing continuous bar, for example:
+// chart.setOption({
+//     visualMap: {type: 'continuous'}
+// });
+// `visualMap` component providing pieces bar, for example:
+// chart.setOption({
+//     visualMap: {type: 'piecewise'}
+// });
