The attribute handling code in the kernel is currently highly duplicated since it needs to handle five different data types and we couldn't use templates back then. We can now, so might as well make use of it and get rid of ~1000 lines. There are also some small fixes for the GPU OSL code: - Wrong derivative for .w component when converting float2/float3->float4 - Different conversion for float2->float (CPU averages, GPU used to take .x) - Removed useless code for converting to float2, not used by OSL Pull Request: https://projects.blender.org/blender/blender/pulls/134694
