Subject: [PATCH] frameworks/base: Swap width and height of temporary buffer
 only with orientation change

Current code swaps the width and height by assuming that aspect
ratio of the buffer width and height will be same as that of the
layout clip width and height. That is not always true.
Change the check to orientation change.
