[GTK][WPE][Skia] Add GPU synchronization primitives to
NativeImage/ImageBuffer for Skia
https://bugs.webkit.org/show_bug.cgi?id=283286
Reviewed by Said Abou-Hallawa.
Prepare for threaded GPU rendering: add Skia specific functions
to ImageBuffer(Backend)/NativeImageBackend:
- finishAcceleratedRenderingAndCreateFence()
Used to notify the underlying SkSurface, that it should flush
all pending rendering operations and submit the work to the GPU.
Afterwards inject a fence into the GL command stream, so that we
we can wait upon completion at a later point, before attempting
to use the ImageBuffer/NativeImage.
- waitForAcceleratedRenderingFenceCompletion()
Performs a 'serverWait()' operation on the GLFence, previously
created by finishAcceleratedRenderingAndCreateFence(). This
instructs to GPU to await completion of the previous rendering.
finishAcceleratedRenderingAndCreateFence() will be used during
DisplayList recording, whenever an ImageBuffer/NativeImage resource
is used, upon entering the DisplayList::ResourceHeap cache.
waitForAcceleratedRenderingFenceCompletion() will be used during
DisplayList replaying, whenever an ImageBuffer/NativeImage resource
is extracted from the DisplayList::ResourceHeap cache.
This PR only contains the Skia specific ImageBuffer/NativeImage related
changes -- the hooks in the DisplayList code that make use of these
methods will be added in a separated PR.
No change in functionality for existing tests.
