[Mesa-dev] [PATCH] st/va: use provided sizes and coords for getimage

[boyuan.zhang at amd.com]

From: Boyuan Zhang <boyuan.zhang at amd.com>

vlVaGetImage should respect the width, height, and coordinates x and y that
passed in. Therefore, pipe_box should be created with the passed in values
instead of surface width/height.
