Spin boxes do not look 100% Cocoa native

Working with Jens on the new desktop components via QML we are trying to get an app that is so pixel perfect no one will even know it is not a Cocoa app. We are finding a ton of issues. As a reference we are using the default components straight out of Xcode 4. Cocoa does not have a SpinBox so we have used the one in the Xcode 4 preferences -> Indention. Some of the issues are coming from using the Cocoa Date Picker as the reference for the SpinBox which is probably not the right thing to do. See attached for the list of issues.
