> There is one more case where one can feel the difference: when selecting with the mouse and dragging to the right, the selection jumps to each character a little "too late", that is, after you have already crossed the position you want the selection to end at. You have to point to a character *after* the one you want to include. The current selection always is up to one character behind the cursor barline.  This results in a "sticky" feeling.

Yes, selection in Emacs works on per-character granularity, because it
uses the faces infrastructure.  We'd need to do something very
different to make that use pixel granularity.  Patches are welcome.
