wxSystemThemedControl allows to use the "system theme" (i.e. the theme used by the system applications such as file manager and which can, surprisingly, be different from the default one). Currently it is only implemented for wxMSW and does nothing under the other platforms. Use wxSystemThemedControl for wxDataViewCtrl, wxListCtrl and, optionally, if wxTR_TWIST_BUTTONS style is specified, wxTreeCtrl to give them more native appearance under MSW. Closes #16414.
