Custom rating bar drawables don't scale
<p>I created a custom rating bar as explained by <a href="http://kozyr.zydako.net/2010/05/23/pretty-ratingbar/" rel="nofollow">kozyr</a> and it works great when I have my rating bar set to the exact dimensions of my full and empty drawables (40dp x40dp) but when I attempt to set the size to something smaller the images are not scaled, they are simply cropped.</p>

<p>Is it possible to scale my rating bar without scaling my actual assets?</p>
