The square root of a sum of squares is easier to read and should be
computed more accurately if done for us by hypot(). Variables set
only once should be set as an initializer and declared const, to make
clear this is what's happening. Loop variables can be local to loops.
Adding a value to, or subtracting one from, a multiple of itself just
multiplies it be one plus (or minus) the multiplier; assigning the
result to the same variable is clearer as a *= (especially when the
factors are now overt numeric constants). An array of 16k floats all
updated in locksteck to the same value can be replaced by a single
float that holds that value. Simple things should not be needlessly
made more complicated - especially in example code, which should be
pedagogic.

M_PI, for consistency. Replaced math.h with qmath.h in places that
defined a fall-back in case math.h omits it (it's not in the C++
standard, although M_PI is in POSIX); or removed this entirely where
it wasn't used.
Reworked some code to reduce the amount of arithmetic needed, in the
process; e.g. pulling common factors out of loops. Revised an
example's doc to not waste time talking about using a six-sig-fig
