[wpe-webkit] Hole punching and WeakRef support in WPE/WebKit v2.22

[Michael Pantazoglou]

Hi all,

I am currently working on an application that uses WPE/WebKit v2.22 and was
wondering, if that older version has support for the following two features:

* WeakRef
I tried to check if WeakRef is available to the JS runtime using remote
debugging tools console, but it seems it is not. Still, I was able to find
some code that is related to the WeakRef implementation:

Source/JavaScriptCore/API/JSWeakPrivate.h
Source/JavaScriptCore/API/JSWeakPrivate.cpp

* Hole Punching
All I found is the following blog post which mentions the hole punching
feature is made available in WPE/WebKit v2.24 and above.

Are those two features supported in v2.22?

Thanks,
Michael
