* Implement "Load Image" popup menu.
* Implement B_COPY_TARGET drop event. People is not (yet) ready to to be itself such target (copying a person picture to another one), though. * Remember the source type and MIME and use them to save the picture in same format when possible. * Avoid flickering when only focus is changing. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40740 a95241bf-73f2-0310-859d-f6bbb57e9c96
