// CheckBox implements a check box button. It uses the standard windows control
// for the check item but not for the label. We have to do this because windows
// always wants to draw a background under the label. I tried to intercept
// WM_CTLCOLORSTATIC and return a NULL_BRUSH and setting the BkMode to
// transparent as well as other things. The background was always drawn as solid
// black.
//
// The label is implemented with a views::Label
