Qt Quick enums must start with a capital letter

Qt Quick appears to require that enums in registered types start with a capital letter.

This isn't mentioned anywhere I could find.

enum EnStyle
{
    STYLE_RADIAL,
    STYLE_ENVELOPE,
    STYLE_FILLED
};
Q_ENUMS(EnStyle)

enum EnStyle
{
    styleRADIAL,
    styleENVELOPE,
    styleFILLED
};
Q_ENUMS(EnStyle)

This should be added to the pages that talk about this:
http://doc.qt.io/qt-5/qtqml-cppintegration-definetypes.html
http://doc.qt.io/qt-5/qqmlengine.html#qmlRegisterType-4
http://doc.qt.io/qt-5/qqmlengine.html#qmlRegisterUncreatableType

(Not sure if this is all, but it's most)
