More than a name change, the painting model changes so that the app, not
the library, is responsible for driving painting. If the app is
animating and wants paint events at 60 Hz, it has to ask for that. If
the app is not animating and doesn't need to update its screen, it
shouldn't get any paint events.
Plenty of TODOs, and this CL doesn't get us to a perfect place, but it
is a checkpoint along the way.
The darwin_*.go code changes were minimal. I don't even have a Mac or
iOS device to test that this even builds. Even so, the TODOs about not
sending paint.Events unconditionally are important TODOs. That's the
whole point of switching to this model. I'll leave the actual
implementation to you (crawshaw).
Out of all the example apps, the change to example/network/main.go is
probably the most interesting.
It seems like there ought to be some way to reduce the copy/paste
between all of the example app code, but I'll leave that for future CLs.

Previously, we did:
for {
processEvents() // Process any pending Android input events.
select { // Select Go events (channel send/receives).
etc
}
}
The problem was that if you were blocked on the select because there
were no incoming Go events, then you weren't reading new input events,
and the UI could block indefinitely.
After this CL, input events are processed in a dedicated goroutine,
where it's fine for
for C.AInputQueue_getEvent(q, &e) >= 0 { etc }
to block, and the main loop deals only with Go channels:
for {
select {
etc
}
}

A framework generated with gomobile bind -target=ios has two global
constructors: one initializing a data structure and another using it.
These constructors are defined in different translation units, which
(I believe, reasoning from C++ global constructors) means their order
of initialization is undefined.
A capturing block is stack allocated. Its memory is invalid after the
function returns. Make a copy of the interface initializer blocks so
they can be saved to the heap.

The former Reader inspired APIs were designed to timeout if no events
occur after an excessive amount of time. As we switch to the app
event based model, timing out is not required. We can block on

1) Clear button did not shrink the WebView size. It's an old bug in
Android WebView, and fixed recently (android-L, maybe). This CL avoids
the problem by replacing the webview with a freshly allocated new webview
object. It's heavy-weight, but the Clear event should be rare.
2) ScrollToBottom from the java side and the java script side interacted
strangely and prevented long results from displayed properly.
Also,
- now the gomobile bind generates the Java class in the
org.golang.ivy package. (ivy/build.gradle)
- modified the javascript in tape.html so long result texts are not
shortened initially. (tape.html)
