59 | * A helper function is provided here to convert from time to process |

61 | * Insert an empty square in the drawing, moving the bottom part. |
62 | * |
63 | * Note: The last point is exactly why it would not be so easy to add the |
64 | * vertical line functionnality as in the original version of LTT. In order |
65 | * to do so, we should keep all processes in the list for the duration of |
66 | * all the trace instead of dynamically adding and removing them when we |
67 | * scroll. Another possibility is to redraw all the visible area when a new |
68 | * process is added to the list. The second solution seems more appropriate |
69 | * to me. |
70 | * |
71 | * |
72 | * The pixmap used has the width of the physical window, but the height |
73 | * of the shown processes. |
