color: move 'write' logic to the core ui class One more step, the support for writing color is not directly in core. No behavior change for the default case ('_colormode' = None). Here are the details of what we have to change to the core method: * apply to 'self.label' to input in the buffered case * dispatch to 'win32print' when applicable * apply to 'self.label' to input when applicable
