           Summary: Affine images are rendered wrong.
           Product: MuPDF
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P4
         Component: fitz

After the image clamp-to-edge code was inserted affine images are misrendered. The current image 
drawing code fills the bounding box that covers the image area with samples taken from the image. This 
means that images that have a non-rectilinear transform (non-90-degree rotation or shearing) will "leak".  
We should use the path scanning logic to fill a rectangular path with image samples instead, and then we 
will also get antialiased image edges as an added bonus.
