    sna/glyphs: Remove glyph_approx_extents

    It didn't consider the height of the glyph above the baseline, i.e. it
    was fundamentally flawed. The only thing to do is to make sure that
    glyph_extents() is sufficiently fast never to show up in profiles.
    (Until then QA should spot the ~10% regression.) An alternative would be
    to feed the drawable clip extents to the render engine and avoid manual
    clipping if the clip region covers the whole drawable.
