QLabel allows scaling of the Pixmap by itself, and we have a FixedAspectRatioLabel that scales a pixmap nicely. Use that. (The new label type needed to be introduced to designer) The screenshot should expand more agressively, so that it does not get margins -- that just leave space around the name and description -- when the window expands. Adjust some of the stretching and layout in the UI file.
