[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.
