Bug 83972 – [Chromium] Add TextureUploader which allows us to use persistent GC3D state for texture uploads.

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[David Reveman]

This is an initial patch to start cleaning up how texture uploads are handled by CCTextureUpdater. It doesn't change the interaction with LayerTextureUpdater. It just creates a TextureUploader class that is similar to the current TextureCopier class and allows us to add persistent state to the upload machinery so that we can land: https://bugs.webkit.org/show_bug.cgi?id=81004

The plan is to follow up with patches that moves a lot of the upload logic from the LayerTextureUpdater and LayerTexureSubImage to this new TextureUploader class.

What would a non-accelerated TextureUploader be, out of curiosity?

Heh, hard to say :) I think this will become SubImageTextureUploader as we move the LayerTexureSubImage logic into the uploader class.
