Ignore Animations/Animator when Transitions run
For a given Fragment, a single owner for its
transition from visible to non-visible is needed
to avoid conflicts as different systems try to
influence the same set of properties.
This has two consequences:
- Animations (which work at the parent container level)
will interfere if there are *any* Transitions run.
- Animators will interfere if there are any Transitions
run on that specific Fragment.
By tracking which Transitions were started and using
that information to selectively ignore conflicting
Animations/Animators, we can avoid visual artifacts.
Test: updated tests pass

There are two parallel systems in Android - the Animation system and the Animator system (which the Transition system is built on top of). With this change and Fragment 1.3.0-alpha08, no Animation will run if there are any Transitions kicked off at the same time and no Animator will run on Fragments that have Transitions directly associated with them (either via an enter/exit transition or as part of a shared element transition).
Description
@Entity(tableName = "purchase_table", ignoredColumns = arrayOf("mParsedJson"))
class CachedPurchase(mOriginalJson: String, mSignature: String) : Purchase(mOriginalJson, mSignature) {
@PrimaryKey(autoGenerate = true)
var id: Int = 0
}
Error:
Room actually generates the correct code, but the compiler still complains about the ignored fields, i.e., "mParsedJson"
