	* Released GooCanvas 0.8

2007-04-03  Damon Chaplin  <damon at gnome.org>

	* demo/mv-demo.c (create_canvas_primitives): 
	* demo/demo.c (create_canvas_primitives): set the maximum scale to 50,
	since if we go above that we hit the cairo 16-bit limit and the large
	rectangle isn't painted correctly.

	* src/goocanvasitemsimple.c (goo_canvas_item_simple_install_common_properties): improved docs for fill/stroke properties.

	* src/goocanvaswidget.c (goo_canvas_widget_new) 
	(goo_canvas_widget_set_widget): keep our own reference to the widget,
	rather than just relying on the canvas widget's reference. Otherwise
	once the widget is removed from the canvas we have an invalid pointer.

+GooCanvas 0.8	(Apr 3 2007)
+=============
+
+ o Added support for "width-for-height" layout - items whose requested
+   height changes according to their allocated width (typically text items).
+ o Added "background-color" and "background-color-rgb" properties to
+   GooCanvas.
+ o Added "ellipsize" property to GooCanvasText.
+ o Added goo_canvas_item_remove() and goo_canvas_item_model_remove()
+   convenience functions to remove an item or model from the canvas.
+ o Fixed bug removing widget items.
+ o Fixed bug which meant that the fill pattern couldn't be reset to NULL.
+ o Fixed the item event signals, so that returning TRUE from a handler
+   stops the signal emission.
+ o Added a few things that will be needed to support tooltips, when GTK+
+   2.12 is available. (Though I don't want to depend on GTK+ 2.12 yet.)
+ o Added "const" to arguments, where appropriate.

 Bugs
 
- o There are no known bugs at present!
+ o Currently the canvas widget must be placed in a GTK+ window before any
+   calls are used that would cause a canvas update.
+   This is because the canvas needs a window to create a cairo_t to do the
+   position calculations. We may use a temporary image cairo_t in future to
+   avoid this issue.
+
+ o I need to check the bounds are being calculated correctly so that they
+   are correct for all zoom settings. Since cairo uses fixed point maths
+   and I think only calculates up to a certain tolerance there might be
+   slight errors in our gdouble results. So as the canvas is scaled this
+   could eventually lead to the bounds being a pixel out, leading to painting
+   errors. Maybe we should extend any bounds returned from cairo slightly to
+   cover the maximum possible errors.
+
+ o GooCanvasImage - redrawing artifacts in demo when zoom>1.
+   Seems to be a bug in cairo, introduced in 1.3.12.
+   See http://bugs.freedesktop.org/show_bug.cgi?id=10508
 
 
 Features definitely needed:
 
  o Editable text item - a port of GtkTextView.
+ o Tooltips - I have code to support tooltips using the new API in GTK+ 2.12.
 
 
 Possible additional features:
 
- o Caching of rendered items to improved performance. Items would have a cache
+ o Caching of rendered items to improve performance. Items would have a cache
    option with choices like Never, Always and WhenVisible.
  o Sticky items that don't move at all as the canvas is scrolled & zoomed.
  o Filters like in SVG, to add graphical effects.
