Converting the LCMS2 transform to a 3D LUT early causes issues: - It's a lossy process, the consumer will not be able to pick a 3D LUT size on their own. - It requires unnecessary conversions and allocations: an intermediate 3D LUT is allocated, but the renderer already allocates one. - It makes it harder to support arbitrary color transforms in the renderer, because each type needs to be handled differently. Instead, expose a function to evaluate a color transform, and use that to build the 3D LUT in the renderer.
