Tor Arne Vestbø 6a35e77ef3 Change confusing Q_DEAD_CODE_FROM_QT4_FOO define 
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To make this even clearer, the defines have been replaced by checks for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.

Qt is provided with a comprehensive canvas through the GraphicsView
classes.

These examples demonstrate the fundamental aspects of canvas programming
with Qt.


Documentation for these examples can be found via the Examples
link in the main Qt documentation.
