-/******************************************************************************
- * Draw_Item.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.
- *

+ * 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.
