	Evas allows for "linear", "radial", "angular", "rectangular"
and "sinusoidal" gradient types, and also two other types of linear
gradients, "linear_diag" and "linear_codiag".

	I moved gradient types to being loadable modules (some time
back now), so you can indeed 'plug-in' new ones.. it just hasn't made
it to cvs yet for various reasons.

	Well, edje actually can have its own degree of freedom in
this respect. You could have 'built-in' types, and just add more
if any are desired in particular.. but you'd either have to add
specific properties/interfaces for describing their particulars,
or go with strings that codify such, as evas now has.

	As to documenting them.. sure, as soon as we can decide
on exactly what properties one wants for these.. The current set
I picked as basic ones that gave 'natural' variability in the
geometries, but there are others - eg. in the SVG spec, radial
gradients allow for 'foci', something which we can add if desired.
	Conversely, if there are things people would like removed,
or modified, then that could be done as well. And improvements,
and whatnot.
	But frankly, I'd like someone else to pick this up if
they wish.. I'm somewhat done with grads for the moment (except
for a couple of pending/past patches), and have little time to
get back to them right now.
