  Fixes for few bugs in reading multi-image gif files by
  Sasha Vasko and Valeriy Onuchin

- TASImage.cxx
  o Several image formats can support subimages e.g.
    GIF, TIFF, BMP, XCF, ICO etc. The famous ones are
    animated GIF files.
    Possiblity to read subimages from multi-image files added.
      For example,
        i1 = TImage::Open("anim.gif.0"); // read the first subimage
        i2 = TImage::Open("anim.gif.1"); // read the second subimage
        i4 = TImage::Open("anim.gif.3"); // read the forth subimage

  o TASImage::Draw method. Take into account the
    gStyle->GetScreenFactor() when a new canvas displaing an image is created.

- TImageDump.cxx
  o Small correction in comment
