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.
