I very much need the ability to have sub-pixel lines and borders for printing purposes. 1-pixel lines are simply too thick to produce professional-quality print output.
Specifically (and echoing WiderGates bug report of Jan 27, 2004), I need widths of: 0.5 pixel, 0.25 pixel, and hairline.
Although the Property Editor for Special Matte borders allow you to enter sub-pixel values, they don’t appear to actually work.
This was a second show-stopper for me, preventing me from converting my project to Servoy (the other being the inablility to have multiple windows).
