Detailed Description
Gradient definition as used in ODF 1.2.This struct collects all data necessary for rendering ODF 1.2-compatible gradients. Use the createXXXODFGradientInfo() methods below for initializing from ODF attributes.

transformation mapping from [0,1]^2 shape coordinate space to [0,1]^2 texture coordinate space.
This is the transformation commonly used to create gradients from a scanline rasterizer (put shape u/v coordinates into it, get texture s/t coordinates out of it)

Aspect ratio of the gradient.
Only used in drawinglayer for generating nested gradient polygons currently. Already catered for in the transformations above.

Requested gradient steps to render.
See the implementations of the getXXXGradientAlpha() methods below, the semantic differs slightly for the different gradient types.
