Use gimp_symmetry_get_transform() instead of
gimp_symmetry_get_operation() throughout the paint code, where
possible. This allows us to combine the symmetry transform with
the ordinary brush transform, simplifying the code, improving
performance, and avoiding multiple resamplings. This also fixes
the paint-buffer size when using mandala symmetry with non-round
brushes, avoiding artifacts.
