QPixmap without QGuiApplication: do not crash, terminate gracefully
Any attempt to create a non-null QPixmap in a QCoreApplication-based
app would give a hard crash without a warning. This commit adds a
check and instead calls qFatal with an explanatory message.
This was originally fixed in Qt 4 (ref. QTBUG-17873) but that was lost
in the migration to Qt 5.
Note that this fix still allows null QPixmaps to be created under
QCoreApplication, since that has worked in all Qt 5 versions.
Task-number: QTBUG-53572
Task-number: QTBUG-64125
