This commit adds interpolation from the point domain to the spline domain and the other way around. Before this, spline domain attributes were basically useless, but now they are quite helpful as a way to use a shared value in a contiguous group of points. I implementented a special virtual array for the spline to points conversion, so that conversion should be close to the ideal performance level, but there are a few ways we could optimize the point to spline conversion in the future: - Use a function virtual array to mix the point values for each spline on demand. - Implement a special case for when the input virtual array is one of the virtual arrays from the spline point attributes. In other words, decrease curve attribute access overhead. Differential Revision: https://developer.blender.org/D11376
