Why did we eliminate this line, given that we inspect the contents of color 2
lines down?

I misunderstood the code and thought these calls were redundant. Updated to just
remove the unused var.

         SkAlpha alpha = skPaint.getAlpha();
         HR(this->createXpsSolidColorBrush(color, alpha, brush));

Why did we eliminate this call, given that we inspect info in the next line of
code?

             SkColor color = info.fColors[0];
