Comment 22 for bug 682338

I'm having trouble applying this patch to libcairo2 version 1.13.0 from Ubuntu 14.04

Doing some tracing, it looks like display->buggy_repeat is accessed by the function:

cairo_bool_t
_cairo_xlib_display_has_repeat (cairo_device_t *device)
{
    return ! ((cairo_xlib_display_t *) device)->buggy_repeat;
}

However, I don't see that function called anywhere else in the code.

I'm still observing slowness for GTK programs using NX (both nx2go and NoMachine).

Could anyone comment on the proper patch for libcairo2 version 1.13.0?

I'm also having trouble locating the callers of _recategorize_composite_operation. Perhaps I have an incomplete source tree?
$ find -type f | xargs grep recategorize_composite
./cairo-xlib-render-compositor.c: operation = _recategorize_composite_operation (dst, op, src, &src_attr,
./cairo-xlib-render-compositor.c: operation = _recategorize_composite_operation (dst, op, src,
