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
