24 * BUGS
25 *
26 * Support PICTYPE_BITMAP and PICTYPE_ICON, although only bitmaps very well..
27 * Lots of methods are just stubs.
28 *
29 *
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).
