-/* This part of the viewer does :
- * Draw horizontal lines, getting graphic context as arg.
- * Copy region of the screen into another.
- * Modify the boundaries to reflect a scale change. (resize)
- * Refresh the physical screen with the pixmap
- * A helper function is provided here to convert from time to process
- * identifier to pixels and the contrary (will be useful for mouse selection).
- * Insert an empty square in the drawing, moving the bottom part.
- *
- * Note: The last point is exactly why it would not be so easy to add the
- * vertical line functionnality as in the original version of LTT. In order
- * to do so, we should keep all processes in the list for the duration of
- * all the trace instead of dynamically adding and removing them when we
- * scroll. Another possibility is to redraw all the visible area when a new
- * process is added to the list. The second solution seems more appropriate
- * to me.
- *
- *
- * The pixmap used has the width of the physical window, but the height
- * of the shown processes.
