[cairo] problem rotating svg

[Russell Strong]

Hi,

I've tried rotating some SVG images and found that parts of the image
aren't behaving correctly.  I'm not sure how to describe it except by
saying run the code and take a look.  The file home.svg comes from
cairo-demo/cairo_snippets/data.

Is it a bug or am I bone?

#!/usr/bin/env python

import gtk
import cairo
import cairo.gtk
import cairo.svg

angle = 0.0

ctx = cairo.svg.Context()
ctx.parse('./home.svg')
sx,sy = ctx.size

def expose_event(widget, event):
        cr = cairo.Context()
        cairo.gtk.set_target_drawable(cr, widget.window)
        cr.translate(400,400)
        cr.rotate(angle)
        cr.translate(-sx/2.0,-sy/2.0)
        ctx.render(cr)

def periodic():
        global angle
        angle = angle + 0.03
        da.queue_draw()
        return True

win = gtk.Window()
da = gtk.DrawingArea()
da.set_size_request(800,800)
win.add(da)
win.show_all()
win.connect('destroy', lambda x:gtk.main_quit())
da.connect('expose_event', expose_event)
gtk.timeout_add(100, periodic)
gtk.main()
