FWIW, I already tried that approach back when Leo ported the outline code to 
RenderInline but I couldn't get it to work perfectly. The problem is the y/x 
banded rectangles you obtain don't have a minimum height... they are 
sometimes even 1 px height.

As a consequence,  it is very tricky to get rid of the painting artifacts at 
vertical segments junction for e.g. dotted borders, or any other fancy border 
style ; it's even harder to deal with correct corner painting, because the 
outlineWidth can be much > to your rectangles' height (and obviously the 
outlineWidth defines the available resolution for the outline shape).
