gradient issues

[Chris Nokleberg <chris@sixlegs.com>]

a) None of the gradient types (linear, axial, radial, ellipsoid, square,
rectangular) are described in terms of how they should be rendered. I
can look at OpenOffice for examples, but that shouldn't be necessary.

b) There is a concentric-gradient-fill-allowed attribute, but there is
no concentric gradient type:

 "The draw:concentric-gradient-fill-allowed attribute specifies if the
  shape is capable being rendered with a concentric gradient that uses
  the custom shape path."

This option was obviously inherited from MS Office (the "from center"
gradient, also see the "gradientshapeok" attribute in VML), but I guess
the gradient type itself didn't make it into the spec because OpenOffice
doesn't support concentric gradients yet?

Thanks,
Chris
