+- Fixes:
+  - Fix rendering corruption triggered occasionally when the compositor is disabled (regression in 0.12.4)
+
+2016-01-23 0.12.4
+- Enhancements:
+  - Support for NETWM viewports (as used by Compiz or Unity) (issue #94)
+  - The default desktop font (Gtk/FontName from XSettings) is used when a font is not specified in the config file
+  - When no fonts are specified in the config, tint2 picks up the default font of the desktop environment via XSettings
+  - Tint2 is now able to dump a stack trace to stderr and ~/.tint2-crash.log in case of a crash.
+    If the cmake flag ENABLE_BACKTRACE is set, stack traces are dumped on X11 I/O errors.
+    If the cmake flag ENABLE_BACKTRACE_ON_SIGNAL is set, stack traces are dumped also on signals such as SIGSEGV.
+    Both ENABLE_BACKTRACE and ENABLE_BACKTRACE_ON_SIGNAL are disabled by default.
+  - Pixmaps are cached instead of always redrawn between different button states when mouse effects are enabled,
+    to improve performance
+  - Tooltips are no longer very wide
+  - Default config looks nicer
+- New config options:
+  - Executor: new plugin that displays the output of a command in the panel (issue #161)
+  - New taskbar sort order options: least-recently-used (lru), most-recently-used (mru) (issue #532)
+  - Place the primary monitor before all the other monitors (primary_monitor_first, issue #538)
+  - taskbar_always_show_all_desktop_tasks (issue #279)
+- Config options with changed behavior:
+  - Mouse effects are enabled by default
+- Fixes:
+  - Battery changes visibility correctly (issue #531)
+  - Fixed rendering corruption (issue #543)
+  - Reverted the window flags back to the value in 0.11 to make sure the window manager detects that tint2 is a panel
+    (affected kwin, bspwm; fixes issue #537, breaks issue #455)
+  - Fixed a rare crash caused by the system tray code
+  - The system tray now reorders icons correctly when the icon name changes and the sorting order is configured as
+    ascending or descending (affected GTK icons, which sometimes set their name late after creating the icon)
+  - Tint2conf no longer copies sample themes to ~/.config
+- New optional dependencies:
+  - libexecinfo on the *BSDs (only if the cmake flag ENABLE_BACKTRACE is set)

-/************************************************************
- * !!! This design is experimental and not yet fully implemented !!!!!!!!!!!!!
- * 
- * DATA ORGANISATION :
- * Areas in tint2 are similar to widgets in a GUI. 
- * All graphical objects (panel, taskbar, task, systray, clock, ...) 'inherit' an abstract class 'Area'.
- * This class 'Area' manage the background, border, size, position and padding.
- * Area is at the begining of each object (&object == &area).
- * 
- * tint2 define one panel per monitor. And each panel have a tree of Area.
- * The root of the tree is Panel.Area. And task, clock, systray, taskbar,... are nodes.
- * 
- * The tree give the localisation of each object :
- * - tree's root is in the background while tree's leafe are foreground objects
- * - position of a node/Area depend on the layout : parent's position (posx, posy), size of previous brothers and parent's padding
- * - size of a node/Area depend on the content (SIZE_BY_CONTENT objects) or on the layout (SIZE_BY_LAYOUT objects) 
- * 
- * DRAWING AND LAYERING ENGINE :
- * Redrawing an object (like the clock) could come from an 'external event' (date change) 
- * or from a 'layering event' (position change).
- * The following 'drawing engine' take care of :
- * - posx/posy of all Area
- * - 'layering event' propagation between object
- * 1) browse tree SIZE_BY_CONTENT
- *  - resize SIZE_BY_CONTENT node : children are resized before parent
- * 	- if 'size' changed then 'resize = 1' on the parent
- * 2) browse tree SIZE_BY_LAYOUT and POSITION
- *  - resize SIZE_BY_LAYOUT node : parent is resized before children
- *  - calculate position (posx,posy) : parent is calculated before children
- * 	- if 'position' changed then 'redraw = 1'
- * 3) browse tree REDRAW
- *  - redraw needed objects : parent is drawn before children
- *
- * CONFIGURE PANEL'S LAYOUT :
- * 'panel_items' parameter (in config) define the list and the order of nodes in tree's panel.
- * 'panel_items = SC' define a panel with just Systray and Clock.
- * So the tree 'Panel.Area' will have 2 childs (Systray and Clock).

+// DATA ORGANISATION
+//
+// Areas in tint2 are similar to widgets in a GUI.
+// All graphical objects (panel, taskbar, task, systray, clock, ...) inherit the abstract class Area.
+// This class 'Area' stores data about the background, border, size, position, padding and the child areas.
+// Inheritance is simulated by having an Area member as the first member of each object (thus &object == &area).
+//
+// tint2 uses multiple panels, one per monitor. Each panel has an area containing the children objects in a tree of
+// areas. The level in the tree gives the z-order: child areas are always displayed on top of their parents.
+//
+//
+// LAYOUT
+//
+// Sibling areas never overlap.
+//
+// The position of an Area (posx, posy) is relative to the window (i.e. absolute) and
+// is computed based on a simple box model:
+// * parent position + parent padding + sum of the sizes of the previous siblings and spacing
+//
+// The size of an Area is:
+// * SIZE_BY_CONTENT objects:
+//   * fixed and set by the Area
+//   * childred are resized before the parent
+//   * if a child size has changed then the parent is resized
+// * SIZE_BY_LAYOUT objects:
+//   * expandable and computed as the total size of the parent - padding -
+//     the size of the fixed sized siblings - spacing and divided by the number of expandable siblings
+//   * the parent is resized before the children
+//
+//
+// RENDERING
+//
+// Redrawing an object (like the clock) could come from an 'external event' (date change)
+// or from a 'layout event' (position change).
+//
+//
+// WIDGET LIFECYCLE
+//
+// Each widget that occurs once per panel is defined as a struct (e.g. Clock) which is stored as a member of Panel.
+// Widgets that can occur more than once should be stored as an array, still as a member of Panel.
+//
+// There is a special Panel instance called 'panel_config' which stores the config options and the state variables
+// of the widgets (however some config options are stored as global variables by the widgets).
+//
+// Tint2 maintains an array of Panel instances, one for each monitor. These contain the actual Areas that are used to
+// render the panels on screen, interact with user input etc.
+// Each Panel is initialized as a raw copy (memcpy, see init_panel()) of panel_config.
+//
+// Normally, widgets should implement the following functions:
+//
+// * void default_widget();
+//
+//   Called before the config is read and panel_config/panels are created.
+//   Afterwards, the config parsing code creates the widget/widget array in panel_config and
+//   populates the configuration fields.
+//   If the widget uses global variables to store config options or other state variables, they should be initialized
+//   here (e.g. with zero, NULL etc).
+//
+// * void init_widget();
+//
+//   Called after the config is read and panel_config is populated, but before panels are created.
+//   Initializes the state of the widget in panel_config.
+//   If the widget uses global variables to store config options or other state variables which depend on the config
+//   options but not on the panel instance, they should be initialized here.
+//   panel_config.panel_items can be used to determine which backend items are enabled.
+//
+// * void init_widget_panel(void *panel);
+//
+//   Called after each on-screen panel is created, with a pointer to the panel.
+//   Completes the initialization of the widget.
+//   At this point the widget Area has not been added yet to the GUI tree, but it will be added right afterwards.
+//
+// * void cleanup_widget();
+//
+//   Called just before the panels are destroyed. Afterwards, tint2 exits or restarts and reads the config again.
+//   Must releases all resources.
+//   The widget itself should not be freed by this function, only its members or global variables that were set.
+//   The widget is freed by the Area tree cleanup function (remove_area).
+//
+// * void draw_widget(void *obj, cairo_t *c);
+//
+//   Called on draw, obj = pointer to the widget instance from the panel that is redrawn.
+//   The Area's _draw_foreground member must point to this function.
+//
+// * int resize_widget(void *obj);
+//
+//   Called on resize, obj = pointer to the front-end Execp item.
+//   Returns 1 if the new size is different than the previous size.
+//   The Area's _resize member must point to this function.
+//
+// * void widget_action(void *obj, int button);
+//
+//   Called on mouse click event.
+//
+// * void widget_on_change_layout(void *obj);
+//
+//   Implemented only to override the default layout algorithm for this widget.
+//   For example, if this widget is a cell in a table, its position and size should be computed here.
+//   The Area's _on_change_layout member must point to this function.
+//
+// * char* widget_get_tooltip_text(void *obj);
+//
+//   Returns a copy of the tooltip to be displayed for this widget.
+//   The caller takes ownership of the pointer.
+//   The Area's _get_tooltip_text member must point to this function.
