Neither example is an easy read - the first could get very difficult with
many color stops.

At http://hpaa.com/csstest/gradient.htm is an image showing a simple top
down gradient with mixed lengths and percentages, similar to the gradient I
gave as an example for considering percentages as applying *between* start,
end, and <length> positions. The inline image of U.S. Houses of Congress
would always be near the middle of the text area, whatever the size of the
text, so positioning the lightest (next-to-last) color stop at 50% of the
span between the last <length> and the end of the gradient will always
highlight the image.

This example could be done with two percentage-only gradients. But I still
think that being able to specify percentages this way opens more
possibilities while it reduces unwanted effects from mixing. And without
altering current behavior in cases where position types are all the same.
