/******************************************************************************
 * drawitem.c
 *
 * This file contains methods responsible for drawing a generic type of data
 * in a drawable. Doing this generically will permit user defined drawing
 * behavior in a later time.
 *
 * This file provides an API which is meant to be reusable for all viewers that
 * need to show information in line, icon, text, background or point form in
 * a drawable area having time for x axis. The y axis, in the control flow
 * viewer case, is corresponding to the different processes, but it can be
 * reused integrally for cpu, and eventually locks, buffers, network
 * interfaces... What will differ between the viewers is the precise
 * information which interests us. We may think that the most useful
 * information for control flow are some specific events, like schedule
 * change, and processes'states. It may differ for a cpu viewer : the
 * interesting information could be more the execution mode of each cpu.
 * This API in meant to make viewer's writers life easier : it will become
 * a simple choice of icons and line types for the precise information
 * the viewer has to provide (agremented with keeping supplementary records
 * and modifying slightly the DrawContext to suit the needs.)
 *
 * We keep each data type in attributes, keys to specific information
 * being formed from the GQuark corresponding to the information received.
 * (facilities / facility_name / events / eventname.)
 * (cpus/cpu_name, process_states/ps_name,
 * execution_modes/em_name, execution_submodes/es_name).
 * The goal is then to provide a generic way to print information on the
 * screen for all this different information.
 *
 * Information can be printed as
 *
 * - text (text + color + size + position (over or under line)
 * - icon (icon filename, corresponding to a loaded icon, accessible through
 *   a GQuark. Icons are loaded statically at the guiControlFlow level during
 *   module initialization and can be added on the fly if not present in the
 *   GQuark.) The habitual place for xpm icons is in
 *   ${prefix}/share/LinuxTraceToolkit.) + position (over or under line)
 * - line (color, width, style)
 * - Arc (big points) (color, size)
 * - background color (color)
 *
 * An item is a leaf of the attributes tree. It is, in that case, including
 * all kind of events categories we can have. It then associates each category
 * with one or more actions (drawing something) or nothing.
 * 
 * Each item has an array of hooks (hook list). Each hook represents an
 * operation to perform. We seek the array each time we want to
 * draw an item. We execute each operation in order. An operation type
 * is associated with each hook to permit user listing and modification
 * of these operations. The operation type is also used to find the
 * corresponding priority for the sorting. Operation type and priorities
 * are enum and a static int table.
 *
 * The array has to be sorted by priority each time we add a task in it.
 * A priority is associated with each operation type. It permits
 * to perform background color selection before line or text drawing. We also
 * draw lines before text, so the text appears over the lines.
 *
 * Executing all the arrays of operations for a specific event (which
 * implies information for state, event, cpu, execution mode and submode)
 * has to be done in a same DrawContext. The goal there is to keep the offset
 * of the text and icons over and under the middle line, so a specific
 * event could be printed as (  R Si 0 for running, scheduled in, cpu 0  ),
 * text being easy to replace with icons. The DrawContext is passed as
 * call_data for the operation hooks.
 *
 * We use the lttv global attributes to keep track of the loaded icons.
 * If we need an icon, we look for it in the icons / icon name pathname.
 * If found, we use the pointer to it. If not, we load the pixmap in
 * memory and set the pointer to the GdkPixmap in the attributes. The
 * structure pointed to contains the pixmap and the mask bitmap.
