/* 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 and process
 * identifier to pixels and the contrary (will be useful for mouse selection).
 * Insert an empty square in the drawing, moving the bottom part.
 *
 * The pixmap used has the width of the physical window, but the height
 * of the shown processes.
