When drawing with a pen for example, the "Hinting" properties tooltip says: "Keep stroke anchors on full pixels to prevent blurry lines."
When I draw zoomed in to 2000%, and set the grid on at one pixel, and check the Hinting property, I don't find anchors snapping to full pixel boundaries. Is this just a limitation of Flash not showing what is actually going on to the user? Meaning, the actual line / anchors are in different positions than what is shown?
If so, I think this is a bug: all sorts of positioning confusion can arise if one is not able to actually see where the lines they have drawn, actually are, for alignment, joining, etc.
