+/* Bug history
+ *
+ * 2005-04-11 Carl Worth <cworth@cworth.org>
+ *
+ *   It appears that calling cairo_show_surface after cairo_translate
+ *   somehow applies the translation twice to the surface being
+ *   shown. This is pretty easy to demonstrate by bringing up xsvg on
+ *   an SVG file with an <image> and panning around a bit with the
+ *   arrow keys.
+ *
+ *   This is almost certainly a regression, and I suspect there may be
+ *   some interaction with the fix for move-to-show-surface.
+ *
+ * 2005-04-12 Carl Worth <cworth@cworth.org>
+ *
+ *   I committed a fix for this bug today.
