If there are more than 7 color stops, we can split the gradient into multiple gradients with color stops like so: 0, 1, 2, 3, 4, 5, transparent transparent, 6, 7, 8, 9, 10, transparent ... transparent, n-2, n-1, n and use the new BLEND_ADD to draw them on top of each other. Adapt the testcae that tests this to use colors that work with the fancy algorithm we use now, so that BLEND_ADD and transitions to transparent do not cause issues.
