For internal use
property FullRedraw: Boolean;
This property is temporal.
If FullRedraw=True, TRichView is redrawn completely when user moves the mouse pointer to the hyperlink area that needs to be highlighted with hovercolor.
If FullRedraw=False, TRichView redraws only the highlighted part (with additional 5 pixels border).
TRichView must be linked with this TRVStyle (see TRichView.Style).
