Fix off by one bug in gesture trail drawing

            float r1 = maxWidth / 2.0f;

            // Initialize bounds rectangle.

            outBoundsRect.set(p1x, p1y, p1x, p1y);

            for (int i = startIndex + 1; i < trailSize - 1; i++) {

            for (int i = startIndex + 1; i < trailSize; i++) {

                final int elapsedTime = sinceDown - eventTimes[i];

                final int p2x = getXCoordValue(xCoords[i]);

                final int p2y = yCoords[i];
