title: android ProgressBar without clipping?
body: <p>Any default ProgressBar has a ClipDrawable level, for example a green Drawable is filling the grey background one on my device, the yellow on some others. </p>

  <p>My question: is that possible to create a ProgressBar without this (partly) empty background when progress is less than max or should I use an ImageView instead? I need only the ClipDrawable to change its width so it looks like a diagram while the grey background never appears. </p>
