Motivation is to disambiguate on the naming level what the matrix actually means. It is very easy to understand the meaning backwards, especially since in Python the name goes the opposite way (it is called `world_matrix` in the Python API). It is important to disambiguate the naming without making developers to look into the comment in the header file (which is also not super clear either). Additionally, more clear naming facilitates the unit verification (or, in this case, space validation) when reading an expression. This patch calls the matrix `object_to_world` which makes it clear from the local code what is it exactly going on. This is only done on DNA level, and a lot of local variables still follow the old naming. A DNA rename is setup in a way that there is no change on the file level, so there should be no regressions at all. The possibility is to add `_matrix` or `_mat` suffix to the name to make it explicit that it is a matrix. Although, not sure if it really helps the readability, or is it something redundant.
