[cairo] problem in _cairo_gstate_glyph_extent today?

[John Ellson]

I updated from CVS this morning and now my code is SIGFPE in the depths 
of cairo.

The problem seems to be an invalid double for dy, but I can't tell how 
it got there.

Has there been a change to the cairo_text_extents API that I need to 
catch up on?
