I felt to be in a maze while reading about gdiplus. I got the feeling
it resembles very much the COM/OLE interface: unintuitive, however,
once grasped then provide a powerful means. Anyway, this study made me
solve (half) the IActiveDesktop problem, which I wanted to use to set
Wallpaper with BMP/JPG/GIF/TIF/PNG, again without the help of
stil32jp.dll or other external tools. Although it'll work only in XP,
it actually doesn't need the ActiveDesktop enabled to use it to set a
wallpaper, I think. Would it be messy to implement this instead in PP?
