Details:

I'm trying to shade part of a view by drawing a partially-transparent shade
of black over it in my drawRect: method. This works fine in Cocoa and in
GNUstep on Linux, but produces solid black on Windows. The code is basically
like this:

                        NSBezierPath *shadePath = [NSBezierPath 
bezierPathWithRect:shadeRect];
                        [[NSColor colorWithCalibratedWhite:0.05 alpha:0.35] 
set];
                        [shadePath fill];
