`fast-inverse-transpose``MATRIX``#!optional``RESULT`procedureEfficiently inverse the transpose the unscaled

`MATRIX`. If`MATRIX`has been scaled, this will produce incorrect results:`inverse`then`transpose`should be used instead. If the matrix`RESULT`is given, it will be modified to contain the result. If`RESULT`is`#t`,`MATRIX`must be an f32vector and the returned value will be an f32vector located in non-garbage-collected memory (the memory will still be freed when there are no more references to the matrix). If`RESULT`is not provided,`MATRIX`must be an f32vector and the returned value will be an f32vector located in normal garbage collected memory.
