I would like to do a non-color gradient, but am not sure how.
For example applying a blur filter in gradient. I.e., imagine the left side of the gradient fill area would be "normal", and as you go right, it would be more and more blury.
I'm exemplifying with "blur", but I need to achieve this with other kinds of filter too. Is there any systematic way of doing it easily?
I am using Inkscape.
