#16 kmzcleanup: better to use <init_planar> for <surface>?

[Anonymous]

SketchUp exports surfaces as
<surface type="2D">
<init_from>material0-image</init_from>
</surface>
which kmzcleanup doesn't change. I was wondering, is this valid? Wouldn't it be better to use
<init_planar>
<all ref=… />
</init_planar>
?
