input: follow the pointer's offset from the press in a split drag

Each motion applied its increment to the split and then reset the origin to the pointer, so a clamp at the minimum share swallowed the overshoot and the split stayed behind the pointer when it came back. The target edge is now the press-time edge plus the offset from the press.
