Test new @reitowo feature on Electron to share a client IOSurface handle with renderer on Electron.

We should test how to implement this new feature #46811 @reitowo created on Electron.

For the time being I'm struggling with building their fork:

gclient config --name "src/electron" --unmanaged https://github.com/reitowo/electron.git
gclient sync --with_branch_heads --with_tags

gave me a 429 error on chromium (limit excedeed) after 4 hour and half.

Trying to resume I have this:

Aborting
error: could not detach HEAD
----------------------------------------
Error: 66> Unrecognized error, please merge or rebase manually.

Following these Electron guidelines I finally have this output : Conflicting directory /[MY_PATH]/electron/src/third_party/angle/third_party/glmark2/src moved to [MY_PATH]/electron/_bad_scm/src/third_party/angle/third_party/glmark2/srcolkbgd1k.

Am I doing something wrong? @RenaudRohlinger any clue 😱 ?

I wouldn't recommend trying to build from scratch, instead I used https://github.com/electron/build-tools on both Windows and Macos:

npm install -g @electron/build-tools
cd C:\path\to\your\workspace
e init my-release --import release
#This creates a configuration named my-release that will generate a Release (out/Release) build.

e sync --revision refs/pull/46811/head
#Sync with the branch of reitowo
e build
#-> will log the output of Electron.app in out/Release

Great! Thank you @RenaudRohlinger.

It's available in Electron alpha now! (Version 40-alpha.5 as of yesterday). Seems to work in my testing https://releases.electronjs.org/release/v40.0.0-alpha.5 (see second feature callout)
