Gallery2: fix screen flashing after rotating pictures

After rotating a picture, it needs to redraw the bitmap,
but the bitmap can not be available immediately, and it will
draw a rectange of placeholder color (gray) first, then it
redraw the bitmap, this make it seems like the screen flashing.

We draw the placeholder color only if the texture is null.
