           Summary: Scrollevents doesn't appear in WindProc of RichTextBox

           Version: 2.4.x
          Platform: x86
        OS/Version: Windows XP
            Status: NEW

Especially when the end of scrolling activity is to be detected, there's only
one way to do this on Windows: overwrite WndProc and look for
WM_HSCROLL/WM_VSCROLL events with SB_ENDSCROLL.
I don't know if this requires a new Winlayer feature and therefore if this is
an enhancement request, but i need this.
So the Message structure should then have WM_HSCROLL/WM_VSCROLL in it's Msg
field and SB_ENDSCROLL (and others) in it's WParam field.

Reproducible: Always
