create_transform_matrix(float[4][4]) did mostly the same as create_transform_matrix(Object *, float[4][4]), but more elegant. However, the former has some inconsistencies with the latter (which are now merged and made explicit, turned out one was for z-up→y-up while the other was for y-up→z-up), and was renamed to copy_m44_axis_swap(...) to convey its purpose more clearly. Furthermore, "loc" has been renamed to "trans", as matrices don't store locations but translations; and more variables now have a src_ or dst_ prefix to denote whether they contain a matrix/vector in the source or destination axis orientation.
