Where that's not available (e.g. fragment shaders), use the same value that qmath.h uses for 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 value for pi (which we no longer do) - it really wasn't relevant, or anything to be proud of; nor did the doc mention its later use.

* Change confusing Q_DEAD_CODE_FROM_QT4_FOO defineTor Arne Vestbø2016-10-141-1/+1
| | | | | | | | | | | | | | | | | | | Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code that the code in question was a left-over from Qt4, when we used Q_WS_ defines instead of Q_OS_ defines. This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually unconditionally included. To make this even clearer, the defines have been replaced by checks for 1 or 0, with a comment describing how the code used to look in Qt4. The use of constants in the check also makes it easier for editors to parse the condition and show visually that the code is defined out.
