Remove ambient clamp hack for analytic shadows.
The hack was added to make analytic ambient shadows match the geometric
ones exactly. Removing it does produce a slight difference, but it's
only visible at full black values (and then, only slightly) and this
makes room to pass a blend parameter for falloff.
Also fixes an issue with filling out arcs in the shadow tesselator.
