Hey folks,
The patch below adds a new PixelsPtr property to Pixbuf, which returns
the same as the Pixels property, except as an IntPtr. This is to
allow C# code to take the pixel data pointer and pass it to more
unmanaged code (non-Gtk), without having to go through an
IntPtr foo;
unsafe { foo = pixbuf.Pixels; }
Let me know if this is okay to commit (or any suggestions on a better
way of doing this :)
