示例1: syncCanvas
void LayerTreeRenderer::syncCanvas(WebLayerID id, const WebCore::IntSize& canvasSize, const GraphicsSurfaceToken& token, uint32_t frontBuffer)
{
if (canvasSize.isEmpty() || !m_textureMapper)
return;
ensureLayer(id);
GraphicsLayer* layer = layerByID(id);
RefPtr<TextureMapperSurfaceBackingStore> canvasBackingStore;
SurfaceBackingStoreMap::iterator it = m_surfaceBackingStores.find(id);
if (it == m_surfaceBackingStores.end()) {
