Turn with_reliable_init into a build function

[mjhouse]

As it stands, with_reliable_init is supposed to be called during construction, as closely as possible to build. Rather than worry about the order of the with_* methods, maybe it should just be another, mutually-exclusive build function that internally calls the first build, then toggles the display some number of times, then returns. The name could be something like build_toggled or build_init or maybe build_stable.

It may also be worth adding a initialize or stabilize method that does the same thing, so that the build method could just call the first build, then call the function, then return.
