Jelle Raaijmakers f8c4043460 LibWeb: Repeat shader for repeating linear gradient 
We implemented repeating linear gradients by expanding a vector of color
stops until the entire range was covered. This is both a bit wasteful
and caused Skia to draw corrupted gradients to screen whenever the total
amount of color stops and positions exceeded 127.

Instead of doing that, use the original color stops for the shader and
repeat it instead of clamping it. We need to do a bit of math to project
positions correctly, but after that the shader repeats itself nicely.

While we're here, calculate the gradient's length and the center point
as floats instead of ints, yielding a slight but noticeable improvement
in gradient rendering (see the diff on the zig zag pattern in
css-gradients.html for an example of this).
