Ignore drag-releases in slider double-click reset; tune HUD slider defaults

A pointer-up after a drag no longer counts as a click (dragging flag +
press-to-release distance within the existing tolerance), so drag ->
release -> click cannot trigger a reset anymore. PaintHud prefab:
pointer tolerance 4 px, HalfLambert default back to 0.5.
