Description Matt Woodrow 2022-09-05 23:29:07 PDT

In order to do GPU rendering from within a WebWorker (bug 218482), we need to be able to create WebKit graphics objects (ChromeClient::createImageBuffer) from the worker thread.

This bug proposes to add a new 'client' WebCoreSupport object 'WorkerClient', which get created for each worker, and allows safe access from the worker thread to a subset of the ChromeClient API.
