I think the concept in Cocoa is that there are NO pixels.
You draw in points (a point is 1/72 of an inch square) in a users
space that is mapped to the device
space of an output device (screen at some resolution, PDF at some
resolution, printer at some resolution, bitmap at some reslution, etc.).
Its all vectors and can be zoomed in to any scale.
Yeah except when having to work with non vector sources (bitmaps,
etc.) but even those can get scaled with high-quality interpolation.
There must be some way to determine the smallest visible line width
or circle though?
What is your goal here? What would you use this knowledge for?
