This is a trivial change which adds virtual methods to View, `onOpen()`
and `onClose()`, which are called when the view is opened or closed.
This information is already tracked inside the View, but not exposed via
the API. There is `didWindowJustOpen()` and `didWindowJustClose()`, but
these fetch and then reset the flag, so they can't be used more than
once in a frame (and are sometimes called by the frame, meaning the flag
has already been consumed by the time the View's draw callback gets
called).
The use case here is that I have a View which needs to do some work
every time it's shown.
Where one door opens, another one closes (said someone) and in this
situation i mean view, because there's no event for closing a view only
opening one, so please add this :c
### Problem description
Simply adds an **EventViewClosed** to match the pre-existing
**EventViewOpened**. Also fixes the issue where EventViewOpened wouldn't
trigger for windows that were popups (even if they are technically a
View.
### Implementation description
I mirrored the current functionality of EventViewOpened for closing.
