Hello.

It is said in the CR (15.5) that

<quote>
It is often necessary to provide padding space because the filter effect
might impact bits slightly outside the tight-fitting bounding box on a
given object. For these purposes, it is possible to provide negative
percentage values for x, y and percentages values greater than 100% for
width, height. For example, x="-10%" y="-10%" width="120%"
height="120%".

However, imagine that the bounding box 'x' is much greater than the bbox
'width', say bbx=1000 and bbwidth=50.
Then the padding space on the x axis would be x=900 (-10% of 1000) and
width=60 (120% of 50).
So at the left of the bounding box you will have a padding space of 100
pixels where you'll have
a padding space of only 10 pixels on the right.

Isn't it a problem ? I mean, if you want a padding space, wouldn't it be
better to have a 'padding-space'
attribute which would be the width of the a band surrounding the bbox ?
