 FrameworkElement::WidthProperty resets cache
 FrameworkElement::HeightProperty sets cache
 
 So for rectangles we compute three times instead of one (or zero,
 since ideally the path doesn't really need to be computed at xaml load
 time).

+using a simple, crude and potentially bad (it may mess with other
+stuff) hack I can avoid 154 rectangles cairo path being "built" when
+starting monotone.
+
+void
+Shape::OnLoaded ()
+{
+       // based on path-caching (won't really work on SVN right now)
+       if (!path) {
+               Invalidate ();
+       }
+       FrameworkElement::OnLoaded ();
+}
+
+Rectangle::Draw (cairo_t *cr)
+{
+       if (!IsLoaded ()) {
+g_warning ("avoided building Rectangle path");
+               return;
+       }
+
+This hack, if working, would be useful when both loading XAML and
+under "normal" (code) circumstances.
