Bug 109659 – Coordinated Graphics : Prevent code duplication of CoordinatedSurface

• Component: Layout and Rendering
• Status: UNCONFIRMED

[Jae Hyun Park]

Many code, especially GraphicsSurface related code, will be shared between WebCoordinatedSurface and WebKit1 CoordinatedSurface.
Therefore, those code should be implemented in CoordinatedSurface.* to prevent from code duplication.

Move some of the duplicated code to CoordinatedSurface.

You can't assume that textureMapper is GL based. You should only do this when isBackedByOpenGL returns true.

This code seems to modify 'CoordinatedSurface.cpp/h' files, which don't exist in WebKit anymore but this commit did seems to highlight renaming:

https://github.com/WebKit/WebKit/commit/fe9d29899711bb87766fd5cb2b2b4f3bbfead88f

So not sure, whether it is needed or not. Appreciate if someone can confirm whether it is needed or not.
