When several painters are defined for the same method and the same direction, Synth takes only the last one. For instance:

<style id="scrollBarThumbStyle">
  <imagePainter method="scrollBarThumbBackground" direction="horizontal" path="images/scrollBar-thumb-horizontal.png" sourceInsets="1 2 1 2" />
  <imagePainter method="scrollBarThumbBackground" direction="horizontal" path="images/scrollBar-thumb-horizontal-grip.png" center="true" />
</style>
<bind style="scrollBarThumbStyle" type="REGION" key="ScrollBarThumb"/>

In this example only the second <imagePainter /> is used by Synth. Both should be used and drawn in the same order of declaration.
