Georges Basile Stavracas Neto 0b4b341e6c clutter/blur: Make sigma a float
The shader already operates on floating point sigma, and
there's just no reason for us to force it to be an unsigned
integer. It's still important that sigma must be positive
though.

Make sigma a float, and make sure it's a positive number.
