When the sane.ds TWAIN data source displays it's user interface, it auto-generates a proprties dialog from the sane options for the current scanner. Oftenly this dialog contains windows ComboBox controls to choose between scan modes (gray / color) or resolutions. The ComboBox controls created are too flat to properly drop down, they only open about half a line height. This is difficult to use. This patch makes the control about 10 times the height of a string. The combox will not occupy more height than the elements that are filled in anyway. Behaviour before the patch: {width=305 height=244} Behaviour after the patch: {width=308 height=246} -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9328
