54 /* This part of the viewer does :
55 * Draw horizontal lines, getting graphic context as arg.
56 * Copy region of the screen into another.
57 * Modify the boundaries to reflect a scale change. (resize)
58 * Refresh the physical screen with the pixmap
59 * A helper function is provided here to convert from time to process
60 * identifier to pixels and the contrary (will be useful for mouse selection).
61 * Insert an empty square in the drawing, moving the bottom part.
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
72 * The pixmap used has the width of the physical window, but the height
73 * of the shown processes.
