The clipboard code now supports the `CF_DIB` format on the clipboard. When found, it takes the data and uses GDI+ to convert it into a JPEG. GDI+ was used because: * It's on every Windows machine from XP SP0 onwards (Win2k doesn't work). * It requires linking to a small gdiplus.lib instead of a massive jpeg library. * It's a really easy interface to use that interops easily with the Windows bitmap header information structures. I think it'd be worth considering this approach for the other screenshot applications as well, as it'd reduce the jpeg lib dependency and simplify the codebase.
