```

## Discussion

Discussion To address window violations in stereo video, the system supports points insetting the left and right edges of the rectangle through additional keys, allowing the description of the extended raster rectangle. The value is a dictionary containing these keys for the extended raster rectangle: kCVImageBufferDisplayMaskRectangle_ReferenceRasterWidthKey kCVImageBufferDisplayMaskRectangle_ReferenceRasterHeightKey kCVImageBufferDisplayMaskRectangle_RectangleLeftKey kCVImageBufferDisplayMaskRectangle_RectangleWidthKey kCVImageBufferDisplayMaskRectangle_RectangleTopKey kCVImageBufferDisplayMaskRectangle_RectangleHeightKey kCVImageBufferDisplayMaskRectangle_LeftEdgePointsKey kCVImageBufferDisplayMaskRectangle_RightEdgePointsKey
