Procedure to get shift_glyphs_for_insert to be called?

[Jan D.]

Hi.

There is a RIF method called shift_glyphs_for_insert.
How do I get it to be called?  I tried many things, but it just seems that the 
entire line gets redrawn every time.

I’m trying to get it to do the right thing in the cairo branch, which it 
currently does not.
But as it it is seldom (never?) called, I have not noticed any redraw errors 
yet.

Thanks,

        Jan D.
