Converts a Blender matrix to an appleseed matrix
We have the following conventions:
Both Blender and appleseed use right-hand coordinate systems.
Both Blender and appleseed use column-major matrices.
Both Blender and appleseed use pre-multiplication.
In Blender, given a matrix m, m[i][j] is the element at the i'th row, j'th column.
The only difference between the coordinate systems of Blender and appleseed is the up vector:
in Blender, up is Z+; in appleseed, up is Y+. So we need to add a -90 degree rotation along the x
axis to translate.
