Description KyungTae Kim 2012-11-07 18:18:40 PST 
With r92340, if no corner intersects the clip region, we pretend outerBorder is rectangular to improve performance.
But in Cairo port, a rounded rect border can look different with a rect border because a complex clip handles different with a simple clip in Cairo.
In mobile environment with floating point zoom, it can cause the inconsistency in border that had been painted on several different tiles.

What do you mean by "handles different with simple clip"? Shouldn't the Cairo backend be fixed then?
