Summary [chromium] Move recursive renderSurface clearing to CCLayerTreeHostImpl

Reported 2012-03-23 14:11:08 PDT
There are a few "unclear" (pun blatantly intended) function names - clearRenderSurface() and clearRenderSurfacesOnCCLayerImplRecursive() and their corresponding functions on CCLayerImpl, too. For readability, we should use more descriptive function names... - LayerRendererChromium::clearSurfaceContents() - LayerRendererChromium::clearRenderSurfacePointers() - CCLayerImpl::clearRenderSurfacePointer()

Comment on attachment 135377 [details] Patch These functions have the same name, but they're in very different types so I'm not sure there is much risk of confusion. I think clearFoo() is fairly well established for clearing an m_foo pointer. I think a better way to disambiguate LayerRendererChromium would be to move this function up to CCLayerTreeHostImpl, where it would fit better

OK sounds good. That means that LRC::close() will also get removed.

Yes, exactly. LayerRendererChromium should be dealing only with GL calls, so 'clear' in that file should always mean something like "do a glClear()". All layer tree lifetime / ownership issues for the impl thread should be dealt with up on CCLayerTreeHostImpl, and CCLayerTreeHostImpl shouldn't know anything about GL, so 'clear' up there should always be doing something to a smart pointer type.
