*
* BUGS
*
* Support PICTYPE_BITMAP and PICTYPE_ICON, although only bitmaps very well..
* Lots of methods are just stubs.
*
*
* NOTES (or things that msdn doesn't tell you)
*
* The width and height properties are returned in HIMETRIC units (0.01mm)
* IPicture::Render also uses these to select a region of the src picture.
* A bitmap's size is converted into these units by using the screen resolution
* thus an 8x8 bitmap on a 96dpi screen has a size of 212x212 (8/96 * 2540).
