Subject: allow disabling throttling in the `viz::DisplayScheduler` per
|
|
`ui::Compositor`
|
|
|
|
In Chromium when the `viz::DisplayScheduler` is invisible it throttles
|
|
its work by dropping frame draws and swaps.
|
|
|
|
This patch allows disbling this throttling by preventing transition to
|
|
invisible state of the `viz::DisplayScheduler` owned
|
|
by the `ui::Compositor`.
