This instructs WinSetWindowPos how
to align valid window bits. This value is made up from CVR_* flags, as follows:
CVR_ALIGNLEFT
Align with the left edge of the window.
CVR_ALIGNBOTTOM
Align with
the bottom edge of the window.
CVR_ALIGNTOP
Align
with the top edge of the window.
CVR_ALIGNRIGHT
Align with the right edge of the window.
CVR_REDRAW
The whole window is invalid. If CVR_REDRAW, is
set, the whole window is assumed invalid, otherwise, the remaining flags
can be ORed together to get different kinds of alignment. For example:
(CVR_ALIGNLEFT | CVR_ALIGNTOP)
aligns the valid window area with the top-left of the window.

It is assumed the application has changed the rectangles
pointed to by pOldNew and pNew itself.
