Dialogs scales icons instead of using provided images
Created originally on Bitbucket by peso (Peer Sommerlund)
On Windows, the dialogs uses one icon for both the small icon in the upper left corner of the dialog and the large icon seen when pressing "Alt-Tab".
Both icon sizes are provided in the .ico files. The bug is that the small icon shown is not the image provided in the .ico file, but a down-scaled version of the large icon.
