Draws stretched and filtered contents of this canvas onto another canvas with pixel blending.

public procedure StretchDrawBlend(const SrcRect: TRect; 
                                  DestCanvas: TImagingCanvas; 
                                  const DestRect: TRect; 
                                  SrcFactor: TBlendingFactor; 
                                  DestFactor: TBlendingFactor; 
                                  Filter: TResizeFilter = rfBilinear);

Blending factors are chosen using TBlendingFactor parameters. Resulting destination pixel color is: SrcColor * SrcFactor + DstColor * DstFactor
