One more question in resetMatrix() method!!!

one more question:

private void resetMatrix() {
mSuppMatrix.reset();
setRotationBy(mBaseRotation);
setImageViewMatrix(getDrawMatrix());
checkMatrixBounds();
}

I think this checkMatrixBounds() method should before setImageViewMatrix(getDrawMatrix());

If "checkMatrixBounds" method modify supportMatrix value, but the imageView is already show it.

What happens? blank area?
