Function node support for blackbody shader node

I went ahead and updated the alpha in the color management generation of blackbody/wavelength to 1.0 after checking existing references of the functions and determining that alpha was previously…

Function node support for blackbody shader node

I feel like a good course of action would be to correct the naming of the `IMB_colormanagement_blackbody_temperature_to_rgb_table` (and single/wavelength functions) to "rgba" and possibly discuss…

Function node support for blackbody shader node

It is a vec4, this is the format that IMB_colormanagement_wavelength_to_rgb_table already assumes. The naming of the original function seems misleading.

Function node support for blackbody shader node

I changed it to a more explicit c array reference similar to the copy_v3_v3 code. The original code set alpha to zero using `r_table[i * 4 + 3] = 0.0f;` this just replicates current behavior.…

Matrix operations and sockets for geometry nodes

For the average user of 3D software they will only ever use location, rotation, and scale. Decomposing is lossy with rotation and scale, therefore not ideal for storing those values to retrieve…

Matrix operations and sockets for geometry nodes

I would personally recommend against going this route and instead present the user with the abstract concept of a transform. Matrices are lossy and can be easily deformed in a way that causes bugs…
