  26  * Support PICTYPE_BITMAP and PICTYPE_ICON, although only bitmaps very well..
  27  * Lots of methods are just stubs.

  30  * NOTES (or things that msdn doesn't tell you)
  31  *
  32  * The width and height properties are returned in HIMETRIC units (0.01mm)
  33  * IPicture::Render also uses these to select a region of the src picture.
  34  * A bitmap's size is converted into these units by using the screen resolution
  35  * thus an 8x8 bitmap on a 96dpi screen has a size of 212x212 (8/96 * 2540).
