Purpose. Nominally: object-hit-testing-aware mouse handlers that additionally report which annotation/field/etc. is under the cursor (Info), with 3/V3 variants scoping the hit-test to an explicit page.

Description — all eight are confirmed complete stubs. Every one of these functions is a single-line body that discards every parameter and returns a zero-valued enum: Result := TPDFCursor(0) (six functions) or Result := TUpdScrollbar(0) (the two Move variants). Info is never written by any of them, CachePtr is never even resolved (no GetCache call), and no cache state is touched — these are pure ABI placeholders. This SDK's *only* real click-driven selection behavior is the plain rasMouseDown/rasMouseMove/ rasMouseUp trio above; there is no working double-click behavior at all, and no mouse event in this entire cluster reports object-hit-test information — a caller wanting that must instead use the separate, explicitly-invoked rasGetObjTypeAt/rasSelectObject functions (Selection, Text, Objects, and Links).

Parameters.

Return value. Always TPDFCursor(0) or TUpdScrollbar(0) (whichever the declared return type is) — not a meaningful cursor or scrollbar-update signal.
