If a transformation matrix causes a scale, a rotation not a multiple of 90 degrees or a non-integral translation then textures rendered with it would benefit from bilinear filtering. This test is done in a lazy fashion by examining elements of the matrix to check for a simple pattern that indicates these conditions are met.
