Update to 1.8.2:

Overview of changes from pycairo 1.8.0 to pycairo 1.8.2
=======================================================

Pycairo 1.8.0 resulted in crashes for some applications using threads. So
upgrading to 1.8.2 is recommended for threaded applications.

Bug Fixes: #19287: Threading support results in crashes in cairo.ImageSurface

New Methods:
    Context.set_scaled_font

API Changes:
    Matrix multiplication:
    old code: matrix3 = matrix1 * matrix2
    new equivalent code: matrix3 = matrix1.multiply(matrix2)
    matrix3 = matrix1 * matrix2
    is now equivalent to matrix3 = matrix2.multiply(matrix1)
    which is consistent with standard matrix multiplication.
