+/******************************************************************************
+ * 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.

+/* Event hooks are the drawing hooks called during traceset read. They draw the
+ * icons, text, lines and background color corresponding to the events read.
+ *
+ * Two hooks are used for drawing : before_schedchange and after_schedchange hooks. The
+ * before_schedchange is called before the state update that occurs with an event and
+ * the after_schedchange hook is called after this state update.
+ *
+ * The before_schedchange hooks fulfill the task of drawing the visible objects that
+ * corresponds to the data accumulated by the after_schedchange hook.
+ *
+ * The after_schedchange hook accumulates the data that need to be shown on the screen
+ * (items) into a queue. Then, the next before_schedchange hook will draw what that
+ * queue contains. That's the Right Way (TM) of drawing items on the screen,
+ * because we need to draw the background first (and then add icons, text, ...
+ * over it), but we only know the length of a background region once the state
+ * corresponding to it is over, which happens to be at the next before_schedchange
+ * hook.
+ *
+ * We also have a hook called at the end of a chunk to draw the information left
+ * undrawn in each process queue. We use the current time as end of
+ * line/background.
