30  *
31  * The width and height properties are returned in HIMETRIC units (0.01mm)
32  * IPicture::Render also uses these to select a region of the src picture.
33  * A bitmap's size is converted into these units by using the screen resolution
34  * thus an 8x8 bitmap on a 96dpi screen has a size of 212x212 (8/96 * 2540).
