GooCanvas 0.15 (Jun 29 2009)
==============
o Fixed a bug that caused a hang when using GooCanvasWidget with
accessibility support turned on.
o Added "scale-to-fit" property to GooCanvasImage, to scale the image
to the "width" and "height" settings, instead of just clipping.
GooCanvas 0.14 (Mar 15 2009)
==============
o Added support for tooltips (this means we need GTK+ 2.12).
(Note that there is a GTK+ bug which will cause problems with
tooltips on a large canvas. See bug #573294.)
o Added "x", "y", "width" and "height" properties to items that
didn't have them.
o Fixed bug in goo_canvas_convert_from_item_space().
o Added "scroll-event" signal to GooCanvasItem.
GooCanvas 0.13 (Nov 30 2008)
==============
o New GooCanvasGrid item for drawing grids on the canvas.
o Support for static items that don't move as the canvas is zoomed
and scrolled (this is a bit experimental).
o Font hinting is not turned off any more - this means smaller text should
be more readable. Hopefully it doesn't affect text layout.
o Fixed a few GooCanvasTable drawing bugs.
o Fixed GooCanvasText drawing, when align is set.
o Fixed GooCanvasPolyline is_item_at() code, so the fill isn't tested.
o Added "animation-finished" signals to GooCanvasItem & Model.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
GooCanvas is similar in many ways to GnomeCanvas and FooCanvas.
But it uses cairo for rendering, has an optional model/view split,
and uses interfaces for items & models (so you can easily turn any
application object into a canvas item or model).
