[Ipe-discuss] Shading definition in stylesheet

[Kostas Oikonomou]

What exactly is the meaning of the "coords" and "extend" attributes used
in shading?  This is from the example stylesheet in the manual:

<shading type="axial" colora="1 0.9 0.5" colorb="1 0.8 0.75"
          coords="0 0 0 200" extend="0 1"/>

For example, is it possible to have a shaded band of a certain height, or
fraction of the vertical size,  at the top of every slide?
How would I specify that?
