Cogl.MatrixStack.prototype.get_inverse

function get_inverse(): [return_value: Cogl.Bool, inverse: Cogl.Matrix] {
    // Gjs wrapper for cogl_matrix_stack_get_inverse()
}

Gets the inverse transform of the current matrix and uses it to initialize a new Cogl.Matrix.

return_value: true if the inverse was successfully calculated or false for degenerate transformations that can't be inverted (in this case the inverse matrix will simply be initialized with the identity matrix)
inverse: The destination for a 4x4 inverse transformation matrix
