Mihai Parparita a39a468f19 Make terminal rendering work in popout windows 
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

Daniel Imms f309affff2 Tweak handling of _contextRestorationTimeout 2022-08-31 05:44:48 -07:00
Kenneth Russell 9459553665 Handle WebGL context loss/restore events in WebGL renderer. 
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.

Svante Boberg 14b02b9ad5 Bump minimum target to es2015 
Now that we no longer support IE we can raise the minimum ES target a
bit. Changing to es2015 shaves off ~17% from the main bundle size, also
it prevents generators from being transpiled into regular functions etc.
so I would guess it has the potential to give some general performance
improvements too.

For fun I also tried to raise it to es2022, this gave a slightly bigger
bundle than es2015 so I think es2015 could be an ok target unless we
need something newer for some reason.
