screenshot

when doing scaling down 4 surfaces into 1 surface with vpp, there are green blocks in the resulted surface as shown in attached screen.

With the attached patch which fixes the green blocks, it also introduces another side effects: the destination height of target scaled image has to be aligned to 32.

We expect libva vpp to scale image as exact specified destination height and width without green blocks.
