qt build fails due to missing #include <QColor>

building Qt fails in \qtwinextras\src\imports\winextras\qquickdwmfeatures_p_p.h:64:12: error: field 'originalSurfaceColor' has incomplete type

with »configure.bat -release -opensource -ltcg -opengl desktop -nomake examples -nomake tools -no-compile-examples -skip webkit -skip doc -no-accessibility«

An `#include <QColor>` in »qquickdwmfeatures_p.h« (note: only one ›_p‹) fixes this.

If you put the include only in »qquickdwmfeatures_p_p.h« (note: two ›_p‹), compile will fail in »moc_qquickdwmfeatures_p.cpp«.

PS: I don’t know to which component »qtwinextras« belongs.
