http://code.google.com/p/chromium-os/issues/detail?id=13821 shows this issue. In chrome, LayerRendererChromium::create might re-enter WebViewImpl::graphicsContext3D, but at that point m_temporaryOnscreenGraphicsContext3D is already reset, whereas m_layerRenderer is not set yet. So we end up creating a new context that isn't used by the compositor, and we then give the compositor a texture ID that doesn't belong to the right context.
This patch makes sure we only reset m_temporaryOnscreenGraphicsContext3D after m_layerRenderer has been set.
