+
+This file documents the common options passed to several map methods.
+
+
+@miniclass Locate options (Map)
+@aka locate options
+@section
+
+Some of the geolocation methods for `Map` take in an `options` parameter. This
+is a plain javascript object with the following optional components:
+
+@option watch: Boolean = false
+If `true`, starts continuous watching of location changes (instead of detecting it
+once) using W3C `watchPosition` method. You can later stop watching using
+`map.stopLocate()` method.
+
+
+@option setView: Boolean = false
+If `true`, automatically sets the map view to the user location with respect to
+detection accuracy, or to world view if geolocation failed.
+
+@option maxZoom: Number = Infinity
+The maximum zoom for automatic view setting when using `setView` option.
+
+@option timeout: Number = 10000
+Number of milliseconds to wait for a response from geolocation before firing a
+`locationerror` event.
+
+@option maximumAge: Number = 0
+Maximum age of detected location. If less than this amount of milliseconds
+passed since last geolocation response, `locate` will return a cached location.
+
+@option enableHighAccuracy: Boolean = false
+Enables high accuracy, see [description in the W3C spec](http://dev.w3.org/geo/api/spec-source.html#high-accuracy).
+
+
+
+@miniclass Zoom options (Map)
+@aka zoom options
+@section
+
+Some of the `Map` methods which modify the zoom level take in an `options`
+parameter. This is a plain javascript object with the following optional
+components:
+
+
+@option animate: Boolean
+If not specified, zoom animation will happen if the zoom origin is inside the
+current view. If `true`, the map will attempt animating zoom disregarding where
+zoom origin is. Setting `false` will make it always reset the view completely
+without animation.
+
+
+
+
+@miniclass Pan options (Map)
+@aka pan options
+@section
+
+Some of the `Map` methods which modify the center of the map take in an `options`
+parameter. This is a plain javascript object with the following optional
+components:
+
+@option animate: Boolean
+If `true`, panning will always be animated if possible. If `false`, it will
+not animate panning, either resetting the map view if panning more than a
+screen away, or just setting a new offset for the map pane (except for `panBy`
+which always does the latter).
+
+@option duration: Number = 0.25
+Duration of animated panning, in seconds.
+
+@option easeLinearity: Number = 0.25
+The curvature factor of panning animation easing (third parameter of the
+[Cubic Bezier curve](http://cubic-bezier.com/)). 1.0 means linear animation,
+and the smaller this number, the more bowed the curve.
+
+@option noMoveStart: Boolean = false
+If `true`, panning won't fire `movestart` event on start (used internally for
+panning inertia).
+
+
+@miniclass Zoom/pan options (Map)
+@aka zoom/pan options
+@inherits Zoom options
+@inherits Pan options
+
+
+@miniclass FitBounds options (Map)
+@aka fitBounds options
+@inherits Zoom/pan options
+
+@option paddingTopLeft: Point = [0, 0]
+Sets the amount of padding in the top left corner of a map container that
+shouldn't be accounted for when setting the view to fit bounds. Useful if you
+have some control overlays on the map like a sidebar and you don't want them
+to obscure objects you're zooming to.
+
+@option paddingBottomRight: Point = [0, 0]
+The same for the bottom right corner of the map.
+
+@option padding: Point = [0, 0]
+Equivalent of setting both top left and bottom right padding to the same value.
+
+@option maxZoom: Number = null
+The maximum possible zoom to use.
