    [MSPAINT][ATL] Encapsulation: mainWindow (#5178)
    
    - Add DoCreate methods to CFullscreenWindow, CMiniatureWindow, and CMainWindow
classes.
    - Do encapsulation around mainWindow and _tWinMain.
    - Add GetOpenFileName, GetSaveFileName, and ChooseColor helper methods to CMainWindow
class.
    - Move some code in WinMain into CMainWindow::OnCreate.
    - Delay creation of CFullscreenWindow and CMiniatureWindow.
    - Extend ATL CImage class as CImageDx in newly-created atlimagedx.h of mspaint.
