pointSetBoundingRect() passed CV_32F coordinates to cvFloor() without
honouring its documented INT_MIN..INT_MAX precondition, so a point set
outside the int range collapsed to a 1x1 rect at INT_MIN, while +inf and
-inf gave INT_MIN and INT_MAX - an inverted rectangle. The extrema are
now searched for in floats, as the vectorized path already did, and
floored and saturated to the closest representable bound once, after the
reduction.
The sides are computed in int64 and clamped to INT_MAX: xmax - xmin + 1
overflows int once the extrema saturate, and did so already for a CV_32S
point set spanning the whole int range.
Fixes#29837
- removed tr1 usage (dropped in C++17)
- moved includes of vector/map/iostream/limits into ts.hpp
- require opencv_test + anonymous namespace (added compile check)
- fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions
- added missing license headers
