1f0bfc8d83 Fix angle discretization in Hough transforms
In some situations the last value was missing from the discrete theta
values. Now, the last value is chosen such that it is close to the
user-provided maximum theta, while the distance to pi remains always
at least theta_step/2. This should avoid duplicate detections.

A better way would probably be to use max_theta as is and adjust the
resolution (theta_step) instead, such that the discretization would
always be uniform (in a circular sense) when full angle range is used.

6a4c3b61e6 Improve doc of calcHist overload that accepts vectors
It's not clear how ranges argument should be used in the overload of
calcHist that accepts std::vector. The main overload uses array of
arrays there, while std::vector overload uses a plain array. The code
interprets the vector as a flattened array and rebuilds array of arrays
from it. This is not obvious interpretation, so documentation has been
added to explain the expected usage.

Replaced sprintf with safer snprintf

* Straightforward replacement of sprintf with safer snprintf

* Trickier replacement of sprintf with safer snprintf

Some functions were changed to take another parameter: the size of the buffer, so that they can pass that size on to snprintf.
