Hi guys,
Do any of you know how the much-talked-about "HiDPI" feature works in Lion? For example, is it a simple 1:2 co-ordinate transformation in both directions? In other words, does it report a logical resolution of only half the physical screen resolution to the application and scale up accordingly (e.g., making lines 2 pixels thick when the application "thinks" it's drawing a line of width 1)? If that's the case, a possible downside would be that the application might pre-trim and/or pre-scale graphic images to the logical pixel dimensions before asking the OS to display them, leaving the OS with no alternative but to scale up to the physical resolution without being able to add any extra detail that may have been present in the original image.
Thanks in advance.
