commit 0ef056230ed50c6cb227cd52ea4b55a3db5f60cb
Author: Benedikt Freisen <b.freisen(a)gmx.net>
AuthorDate: Wed Nov 1 14:59:01 2017 +0100

    [MSPAINT] Base dialog implementations on CDialogImpl
    
    - Wrap implementation of Mirror/Rotate, Stretch/Skew and Attributes dialog in
subclasses of CDialogImpl
    - Turn global variables from code that was moved into member functions into member
variables
    - Add global instances of all three dialog classes
    - Use <global instance>.DoModal(...) instead of one-line wrappers
    - Replace some TCHAR arrays with CStrings
