         https://bugs.webkit.org/show_bug.cgi?id=60317
 
         Stop scaling the specified font to the actual on-screen value when font-rendering: 
         geometricPrecision is specified, but instead scale the graphics context. This allows

+        to return a non-null pointer. Thus null-check here like the rest of the code.
