+"""A Telemetry page_action that performs the "drag" action on pages. |
+ |
+Action parameters are: |
+- selector: If no selector is defined then the action attempts to drag the |
+ document element on the page. |
+- element_function: CSS selector used to evaluate callback when test completes |
+- text: The element with exact text is selected. |
+- left_start_ratio: ratio of start point's left coordinate to the element |
+ width. |
+- top_start_ratio: ratio of start point's top coordinate to the element height. |
+- left_end_ratio: ratio of end point's left coordinate to the element width. |
+- left_end_ratio: ratio of end point's top coordinate to the element height. |
+- speed_in_pixels_per_second: speed of the drag gesture in pixels per second. |
+- use_touch: boolean value to specify if gesture should use touch input or not. |
