   2  * OLE Picture object

   4  * Implementation of OLE IPicture and related interfaces

   7  *
   8  *
   9  * BUGS
  10  *
  11  * Only implements PICTYPE_BITMAP.
  12  * Most methods are just stubs.
  13  * Doesn't even expose IPersistStream, IConnectionPointContainer.
  14  *
  15  *
  16  * NOTES (or things that msdn doesn't tell you)
  17  *
  18  * The width and height properties are returned in HIMETRIC units (0.01mm)
  19  * IPicture::Render also uses these to select a region of the src picture.
  20  * A bitmap's size is converted into these units by using the screen resolution
  21  * thus an 8x8 bitmap on a 96dpi screen has a size of 212x212 (8/96 * 2540).
