cocoa: Don't change the NSWindow background color. Changing the background color causes the titlebar to blend against it on modern macOS releases, making all SDL windows look wrong by default. This was set to make the window not flash white before a GL context is ready, but we can accomplish this in our window's view's drawRect implementation, too.
