Bugs

 o Demo text layout is changing when scale is 0.65. Maybe bug 341481.
 o Text item view bounds should use ink rect.


Plans for next release:

 o Support different units. Currently we assume everything is in pixels.
 o Support for containers similar to widgets like GtkTable. These would do
   a size-request/size-allocate procedure, and so would probably need to the
   current update methods.


Features definitely needed:

 o Editable text item - a port of GtkTextView.


Possible additional features:

 o Sticky items that don't move at all as the canvas is scrolled & zoomed.
 o Clip paths/masks for items.
 o Filters like in SVG, to add graphical effects.
 o Support using the same item in different places, like SVG 'use'.
 o Support using system color names, like SVG, e.g. "ActiveBorder".
   This helps you write widget-like items that fit in with the rest of GTK+.
