private int computeReleaseOffset(int space) {
    // This is simpler than it looks: we must pass whole lines.
    String logPrefix = logPrefix();
    Layout layout = mView.getLayout();
    int count = layout.getLineCount();
    int removed = 0;
    LOG.v(logPrefix, "computeReleaseOffset:", "space:", space, "lineCount:", count);
    int removeLine = 0;
    for (int i = count - 1; i >= 0; i--) {
        layout.getLineBounds(i, mTmp);
        removed += mTmp.height();
        if (removed >= space) {
            removeLine = i;
            break;
        }
    }
    // We have to remove line i and all subsequent lines.
    LOG.i(logPrefix, "computeReleaseOffset:", "removing line:", removeLine, "and subsequent.");
    return Math.max(layout.getOffsetForHorizontal(removeLine, 0) - 1, 0);
