Question for Guillaume about b30f8d3c and GuiFontMetrics::countExpanders

[Jean-Marc Lasgouttes]

Hi Guillaume,
The commit log for b30f8d3c says: " CountExpanders() is moved to 
FontMetrics to fix a discrepancy with the duplicate implementation from 
598f7e4a."

I interpret that to mean that countExpanders() should be available in 
GuiPainter too, right?

OTOH, countExpanders is basically a plain function and it seems weird to 
require a FontMetrics object to compute it.

Is there a reason why it is not a free standing function somewhere in 
support/ ?

JMarc
