Creates a mask layer.
It should be added in a Map
to be displayed in the instance.
See the example for more information on layer creation.

userAn object that can be used to store custom data about the Layer.
Gets or sets the brightness of this layer.
Gets the colorimetry parameters of this layer.
Gets or sets the contrast of this layer.
Gets the elevation range of this layer, if any.
Sets the elevation range of this layer. Setting it to null removes the elevation range.
Gets whether the object is currently performing an asynchronous operation.
Gets or sets the opacity of this layer.
Returns the percentage of progress, in normalized value (i.e in the [0, 1] range), of the asynchronous operations that are scheduled to run on this object. 1 means that all operations have finished.
Gets or sets the saturation of this layer.
Gets or sets the visibility of this layer.

target: MemoryUsageReportIf specified, the values computed during this call must be added to the existing values in the target. Otherwise, a new report must be built.
The memory usage report. If target is specified, then this must be returned.
Get all features whose bounding box intersects the provided extent. Note that this returns an array of all features intersecting the given extent in random order (so it may include features whose geometries do not intersect the extent).
Array of features intersecting the extent (can be empty)

A ColorLayer that can be used to mask parts of a map. The source can be any source supported by the color layers.
