No issue - Set device contrast to an acceptable value if OOB.

Browse source 
On Mac and Win+DW, enhanced device contrast can possibly not be set.
This throws Skia for a loop by passing in an OOB scalar to its init.
Work around this by setting an accepted average value that helps
prevent font wash-out while not causing fringing.
