| A pipeline to test navigation events. |
| While moving the mouse pointer over the test signal you will see a black box |
| following the mouse pointer. If you press the mouse button somewhere on the |
| video and release it somewhere else a green box will appear where you pressed |
| the button and a red one where you released it. (The navigationtest element |
| is part of gst-plugins-good.) You can observe here that even if the images |
| are scaled through hardware the pointer coordinates are converted back to the |
| original video frame geometry so that the box can be drawn to the correct |
| position. This also handles borders correctly, limiting coordinates to the |
| image area |
