henry.uh_chen 20adb6ce4d [HWUI]: fix residual line on FrameBuffer
Symptom: If app applies animation to enlarge a bitmap, there will be an residual
         line on the screen

Root Cause: On platform which has Tile Rendering implementation (ex. Qualcomm
            CPU), startTiling() call will restrict the framebuffer region which
            GPU can affect. So the expansion of clear region by 1 will not take
            effect if startTiling region is not expanded.

Solution: Expand the startTiling region by 1, too.

Reproduce steps: Apply animation to enlarge (and then shrink) a bitmap icon.
