title: Is it possible to draw dot using android.graphics.Path
body: <p>I am writing simple android application for drawing on screen based on FingerPaint API demo example. In the demo drawing begins only after finger has traveled certain distance on screen defined by TOUCH_TOLERANCE. I'd like to draw a dot even if user doesn't move the finger. Is it possible?</p>

      protected void onDraw(Canvas canvas) {
          canvas.drawColor(0xFFAAAAAA);
          canvas.drawBitmap(mBitmap, 0, 0, mBitmapPaint);
          canvas.drawPath(mPath, mPaint);
      }
  
      private float mX, mY;
      private static final float TOUCH_TOLERANCE = 4;
  
      private void touch_start(float x, float y) {
          mPath.reset();
          mPath.moveTo(x, y);
          //mPath.lineTo(x + 1, y + 1); //quick fix
          mX = x;
          mY = y;
      }
      private void touch_move(float x, float y) {
          float dx = Math.abs(x - mX);
          float dy = Math.abs(y - mY);
          if (dx &gt;= TOUCH_TOLERANCE || dy &gt;= TOUCH_TOLERANCE) {
              mPath.quadTo(mX, mY, (x + mX)/2, (y + mY)/2);
              mX = x;

          // kill this so we don't double draw
          mPath.reset();
