<animatorgroup> (and hence <animator>) have some complexities in their API that
I would like to clean up in 5.0:
Attributes:
+ `start`: is effectively write-only and collides with the event `onstart`
which it only indirectly effects.
The value of `start` is currently stored in the attribute `started`, but if you
change the value of `started` it will _not_ have the same effect as changing
`start`.
I propose we deprecate `start` and replace it with `started` (or perhaps, since
we are changing it, use a more descriptive term like `autostart`); in a
subsequent release we can remove `start` altogether as an attribute.
+ `isactive`: should have been a private attribute
I propose that it be deprecated and made private in a subsequent release.
Methods:
`doStart` => `setAttribute('started', true)`
`stop` => `setAttribute('started', false)`
If we choose a different name for `started`, obviously that would be applied
here.
I propose that these methods be deprecated and made private in a subsequent
release.
Events:
It seems it would also be nice if we could have the tense of the events agree.
We currently have `onstart`, `onpaused`, `onstop`. If we don't use `started`
as an attribute, we could make these be `onstarted`, `onpaused`, and
`onstopped`. But perhaps that is going too far?
Your comments solicited.
