Bool ScrollTo (wxSnip *snip, float localx, float localy, float w, float h, Bool refresh, int bias = 0)
Causes the owning buffer to scroll the display so that the given region of the specified snip is visible. localx and localy are relative to the top-left of the snip.
The the entire region does not fit in the visible area, then bias specifies which end of the range should be made visible; -1 means the top-left, and 1 means the bottom-right.
