+/* SetHatchWindowSize
+ *
+ *

+ *      in-place container. both rect's are expressed in the client coord.
+ *      of the in-place container's window (which is the parent of the
+ *      HatchWindow).
+ *
+ *      OLE2NOTE: the in-place server must honor the lprcClipRect specified
+ *      by its in-place container. it must NOT draw outside of the ClipRect.
+ *      in order to achieve this, the hatch window is sized to be
+ *      exactly the size that should be visible (rcVisRect). the
+ *      rcVisRect is defined as the intersection of the full size of
+ *      the HatchRect window and the lprcClipRect.
+ *      the ClipRect could infact clip the HatchRect on the
+ *      right/bottom and/or on the top/left. if it is clipped on the
+ *      right/bottom then it is sufficient to simply resize the hatch
+ *      window. but if the HatchRect is clipped on the top/left then
+ *      in-place server document window (child of HatchWindow) must be moved
+ *      by the delta that was clipped. the window origin of the
+ *      in-place server window will then have negative coordinates relative
+ *      to its parent HatchWindow.
+ *
+ *  Parameters:
+ *      hWndHatch       hatch window handle
+ *      lprcIPObjRect   full size of in-place server object window
+ *      lprcClipRect    clipping rect imposed by in-place container
+ *      lpptOffset      offset required to position in-place server object
+ *                      window properly. caller should call:
+ *                          OffsetRect(&rcObjRect,lpptOffset->x,lpptOffset->y)
