Ok, that was just me being a bit sloppy with the definition. We should
probably add "play speed" to the input at some point as well, but that can
wait.

For positioning an input, I assumed that there would be a seperate
"translation, rotation and scaling" effect that would handle this.
e,g,
<translate>
<inputs>
<input file="test.avi" start="0.0" length="60.0"/>
</inputs>
<position>
<keyframe time="0.0" type="step">
<coordinate x="768" y="0"/>
</keyframe>
<keyframe time="3.0" type="linear">
<coordinate x="0" y="0"/>
</keyframe>
</translation>
</translate>
Effects are not defined in the scene structure in any great depth, because the
parameters and the number of inputs will vary between different effects. This
is why I suggested that we need the effect part of the cutter capabilities
for when we implement effects in the storyboard description, as this makes
the effect descriptions generic, rather than hard-coded.
Cheers,
Jason
