colormap filter testing

For testing out a brand new inkscape extension, generating colormap filters.
Top row shows the gradient which the filter was generated from.
Following rows show black to white gradients with filters applied.
First, the one generated with the extension.
Next, a bit modified version -which has a little bit of rendering issue in 0.91-.
And right below is one with a filter variant, where an "unnecessary" component transfer is rigged in as well.
Last row shows if that component transfer is adjusted, you can fit the mapped gradient better to the tone range of the source, whatever it may be (missing black or white tones etc.).
