Make the tooltip menupopup view not go through VibrancyManager at all (don't really need to). Use an EnumeratedArray for storage rather than a hashmap. Differential Revision: https://phabricator.services.mozilla.com/D207390

* VibrancyManager takes care of updating the vibrant regions of a window.
|
|
* Vibrancy is a visual look that was introduced on OS X starting with 10.10.
|
|
* An app declares vibrant window regions to the window server, and the window
|
|
* server will display a blurred rendering of the screen contents from behind
|
|
* the window in these areas, behind the actual window contents. Consequently,
|
|
* the effect is only visible in areas where the window contents are not
|
|
* completely opaque. Usually this is achieved by clearing the background of
|
|
* the window prior to drawing in the vibrant areas. This is possible even if
|
|
* the window is declared as opaque.
