cursor-type as bar

[Markus Gritsch]

Hi,

I would like to use a bar cursor, instead of a block cursor.
(setq default-frame-alist '((cursor-type . (bar . 2))))

The problem is, that the bar cursor is drawn like a block cursor, only 
using a smaller width. To really be usable, the bar cursor should be 
drawn *between* the characters, e.g. shifting it width/2 pixels to the left.

On the attached Emacs.png the 'u' is partially hiden by the bar-cursor. 
 It is even worse when the cursor is placed at the 'i', in which case 
the letter is hidden completely.  The attachment SciTE.png shows a 
screenshot of the OpenSource Scintilla text editing widget, which shifts 
a 2 pixel wide bar-cursor one pixel to the left.

Kind regards,
Markus
