Error when translate a point

See original GitHub issue

Expected behavior and actual behavior.

Something in the last release (1.8.3) seems to cause an error when translate a point. Working fine with polygons.

Steps to reproduce the problem.

from shapely.geometry import Point
from shapely import affinity
affinity.translate(Point(10, 10), 50, 50)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/tmp/t/venv/lib/python3.8/site-packages/shapely/affinity.py", line 264, in translate
    return affine_transform(geom, matrix)
  File "/tmp/t/venv/lib/python3.8/site-packages/shapely/speedups/__init__.py", line 73, in affine_transform
    return _speedups.affine_transform(geom, matrix)
  File "shapely/speedups/_speedups.pyx", line 521, in shapely.speedups._speedups.affine_transform
  File "shapely/speedups/_speedups.pyx", line 553, in shapely.speedups._speedups.affine_transform
TypeError: an integer is required

So the underlying reason here is that _geom / __geom__ no longer is an int:

In [3]: Point(10, 10).__geom__
Out[3]: <shapely.ctypes_declarations.LP_GEOSGeom_t at 0x7fbcf08ce5c0>

We are seeing similar problems in geopandas (with conversion to pygeos): https://github.com/geopandas/geopandas/issues/2531. So ideally we would solve this by changing __geom__ back to an int, and not by updating our internal code to deal with the changed return value.

Resolved by #1487. @johnnv1 @jorisvandenbossche new distributions are uploading to PyPI now.
