<pre>commit ec0866e86d365ae3fd9790b1b263d49fc4981220

sna/glyphs: Fix computation of extents for long strings
And make sure we consider such overflowing strings for correct clipping
against Windows.
To offset the cost of doing a full extents check (~10% on aa10text), we
introduce an approximate extents query (~1% on aa10text). The disparity
should be rare, and should be an overestimate to force redundant
clipping.
