Provide a DebugLayerManager for mskp files containing layer information when set this DebugCanvas will attempt to parse layer info from annotations. it will store layer pictures to the layer manager, and interpret some drawImageRects as layer draws, deferring to the layer manager for images. Provide a frame number that will be passed to all layer manager functions to identify this DebugCanvas.
