Add support for the parent element (what is passed to Terminal.open)
being in a different (same origin) window. Accesses to DOM APIs such
as requestAnimationFrame and devicePixelRatio thus need to be scoped
to the corrent window, instead of assuming that it's the same as the
window/global scope where the code is running.
This is done by inferring a parent window at the creation time, and
then storing it in CoreBrowserService, which is already passed to most
places that need it.
To catch future regressions, an ESLint rule that checks for global
accesses is added (it uses AST selectors via the no-restricted-syntax
rule).
This should also be applicable when the parent element is an iframe.
Fixes#3758
If the context is restored within a brief period of time (3 seconds),
recreate members dependent on WebGL state, and fire onRequestRedraw to
the renderer's listeners.
Handle changes to the char atlas better in the demo client.
Tested in Chrome Canary on macOS by running the demo in one window,
and visiting the internal URL about:gpucrash in another window. The
terminal now recovers and redraws properly.
This makes it consistent with selectionForeground and other theme keys and
as a result will make the API easier to work with, especially when inactive
selection is done (#3803)
This uses the ResizeObserver devicePixelContentBoxSize API in order to
fetch the exact device pixel dimensions from the browser. The old
possibly blurry behavior is used as a fallback if that API is not
available.

The following parts were not respecting the column selection edge case where the
start column was greater than the end column while the start row was less than the
end row:
- Webgl renderer
- DOM renderer
- Selection service (ie. getSelection(), I don't think this was a
regression)
Fixes#3855
