| +"""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. |
