示例1: shouldRepaintSubsequence
static bool shouldRepaintSubsequence(PaintLayer& paintLayer, const PaintLayerPaintingInfo& paintingInfo, ShouldRespectOverflowClip respectOverflowClip, const LayoutSize& subpixelAccumulation)
{
bool needsRepaint = false;
// Repaint subsequence if the layer is marked for needing repaint.
if (paintLayer.needsRepaint())
needsRepaint = true;
// Repaint if layer's clip changes.
ClipRects& clipRects = paintLayer.clipper().paintingClipRects(paintingInfo.rootLayer, respectOverflowClip, subpixelAccumulation);
ClipRects* previousClipRects = paintLayer.previousPaintingClipRects();
if (!needsRepaint && &clipRects != previousClipRects && (!previousClipRects || clipRects != *previousClipRects))
needsRepaint = true;
paintLayer.setPreviousPaintingClipRects(clipRects);
// Repaint if previously the layer might be clipped by paintDirtyRect and paintDirtyRect changes.
if (!needsRepaint && paintLayer.previousPaintResult() == PaintLayerPainter::MayBeClippedByPaintDirtyRect && paintLayer.previousPaintDirtyRect() != paintingInfo.paintDirtyRect)
needsRepaint = true;
paintLayer.setPreviousPaintDirtyRect(paintingInfo.paintDirtyRect);
// Repaint if scroll offset accumulation changes.
