* generic/ttk/ttkWidget.c: Split up RedisplayWidget()
to factor out double-buffering related code. * macosx/ttkMacOSXAquaTheme.c: Use SetThemeBackGround/ kThemeBrushModelessDialogBackground{Active|Inactive} instead of ApplyThemeBackground/kThemeBackgroundWindowHeader (advice from DAS). * library/ttk/aquaTheme.tcl: Use darker shade for inactive and disabled text, to match typical values of most kThemeXXXTextColorInactive values.
