23 * BUGS
24 *
25 * Support PICTYPE_BITMAP and PICTYPE_ICON, altough only bitmaps very well..
26 * Lots of methods are just stubs.
27 *
28 *
29 * NOTES (or things that msdn doesn't tell you)
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).
