Merge pull request #21677 from chacha21:rectangle_intersection
* better accuracy of _rotatedRectangleIntersection

instead of just migrating to double-precision (which would work), some computations are scaled by a factor that depends on the length of the smallest vectors.
There is a better accuracy even with floats, so this is certainly better for very sensitive cases

* Update intersection.cpp

use L2SQR norm to tune the numeric scale

* Update intersection.cpp

adapt samePointEps with L2 norm

* Update intersection.cpp

move comment

* Update intersection.cpp

fix wrong numericalScalingFactor usage

* added tests

* fixed warnings returned by buildbot

* modifications suggested by reviewer

renaming numericalScaleFctor to normalizationScale
refactor some computations
more "const"

* modifications as suggested by reviewer

Merge pull request #21258 from eplankin:fix_threshold_to_zero_ipp_bug
Fixed threshold(THRESH_TOZERO) at imgproc(IPP)

* Fixed #16085: imgproc(IPP): wrong result from threshold(THRESH_TOZERO)

2. Used nextafterf instead of cast to hex

* Used float value in test instead of hex and casts

* Changed input value in test

3da17c42a4 Use NaN-safe clip function.
This is to prevent more NaN to int conversions like in #21111.

Merge pull request #19842 from gasparitiago:3.4
Update rotatedRectangleIntersection function to calculate near to origin

* Change type used in points function from RotatedRect

In the function that sets the points of a RotatedRect, the types

should be double in order to keep the precision when dealing with
RotatedRects that are defined far from the origin.

This commit solves the problem in some assertions from
rotatedRectangleIntersection when dealing with rectangles far from
origin.

* added proper type casts

* Update rotatedRectangleIntersection function to calculate near to origin

This commit changes the rotatedRectangleIntersection function in order
to calculate the intersection of two rectangles considering that they
are shifted near the coordinates origin (0, 0).

This commit solves the problem in some assertions from
rotatedRectangleIntersection when dealing with rectangles far from
origin.

* Revert type changes in types.cpp and adequate code to c++98

* Revert unnecessary casts on types.cpp
