Re: affine_rotate a text canvas item

[Ryan Gammon <rggammon alumni uwaterloo ca>]

GnomeCanvasHacktext seems to do the trick. There's a typo in 
gnome-canvas-hacktext.c (part of libgnomeprintui-1.116.0)

-    gtk_object_add_arg_type ("GnomeCanvasHacktext::font", 
GTK_TYPE_OBJECT, GTK_ARG_READWRITE, ARG_FONT);
+    gtk_object_add_arg_type ("GnomeCanvasHacktext::font", 
GTK_TYPE_POINTER, GTK_ARG_READWRITE, ARG_FONT);


What stops rotation from working with the stock GnomeCanvasText item? Is 
this something that needs to be implemented in pango?
