[Qt][WK2] Remove TiledDrawingArea and dependencies.

[alan]

TiledDrawingArea and its dependencies are obsolete. In case that any port needs same/similar functionality, the current class structure needs to be reconsidered. Currently there are lots of duplicated code in TiledDrawingAreaProxy and DrawingAreaImpl. Either Tiled needs to be derived from Impl, or preferably Impl code should be moved up to the base class.

Hi, zbujtas,

The internal version of WK2-efl's tiled backing store implementation is now based on TiledDrawingArea.

So, I would like to know the next plan after landing of this patch.
Should we have to move from TiledDrawingArea to DrawingArea or LayerTreeHost ?

It's really up to you whether you'd like to keep the original tile approach with a little bit of different class structure (see comment#2). However, that most likely will not work properly in all the cases when both AC and non-AC content are present. Or, as you mentioned, follow the LayerTreeHost(Qt) (TiledBackingStoreRemoteTile) implementation, which properly synchronizes the non-AC with the AC content using tiles. https://bugs.webkit.org/show_bug.cgi?id=69151

Could you let me know, if you are fine with removing these classes? (would be great to know before submitting it for review)

Hi, zbujtas,

I am gathering idea from each related person to know whether anybody has any major issue caused by this patch. :)
I will give you any feedback for this soon.

I sincerely thank you for your notification of this patch in advance.

LGTM.

We are going to move into LayerTreeHost sooner or later.
However, I prefer it if you remove these files some days later. :)
