Fixes two related bugs:

. Native buttons were adding 8 pixels to each side of the preferred
  size. This isn't necessary on Gtk as the preferred size already
  includes padding.
. I changed WidgetGtk so that it no longer needs to explicitly set a
  size request. Explicitly setting a size request is a bit of pain
  because it means you can't ask for the widget real size request
  without unsetting the explicit size request. Instead I've subclassed
  GtkFixed so that you can either have the default behavior, or use
  the allocated size rather than current size.
