/**
NM_FIREVIEWCHANGE is WM_NOTIFY Message for notify parent of host window about smiley are going to be repaint
The proposed action is next: Owner of RichEdit windows received NM_FIREVIEWCHANGE through WM_NOTIFY
twice first time before painting|invalidating (FVCN_PREFIRE) and second time - after (FVCN_POSTFIRE).
The Owner window may change any values of received FVCNDATA_NMHDR structure in order to raise needed action.
For example it may substitute FVCA_INVALIDATE to FVCA_CUSTOMDRAW event to force painting on self offscreen context.
It can be:
FVCA_CUSTOMDRAW - in this case you need to provide valid HDC to draw on and valid RECT of smiley
FVCA_INVALIDATE - to invalidate specified rect of window
FVCA_NONE - skip any action. But be aware - animation will be stopped till next repainting of smiley.
FVCA_SENDVIEWCHANGE - to notify richedit ole about object changed. Be aware Richedit will fully reconstruct itself
Another point is moment of received smiley rect - it is only valid if FVCA_DRAW is initially set,
and it is PROBABLY valid if FVCA_INVALIDATE is set. And it most probably invalid in case of FVCA_SENDVIEWCHANGE.
The smiley position is relative last full paint HDC. Usually it is relative to top-left corner of host
richedit (NOT it client area) in windows coordinates.
