Selection
Selection on curves can be stored on either attribute domain: either per-curve or per-point. It can be stored with a float or boolean data-type. The boolean data-type is faster, smaller, and corresponds better to edit-mode selections, but the float data type is useful for soft selection (like masking) in sculpt mode. The attribute API is used to do the necessary type and domain conversions when necessary, and can handle most interaction with the selection attribute, but these functions implement some helpful utilities on top of that.
