Merge branch 'master' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into master-integration

* 'master' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
  qdrawhelper: Use SSE2 in fetchTransformedBilinear (when scalling up)
  QListView: speedup QListView::setRowHidden()
  Remove debug info from tst_QGlyphs
  Fix tst_QGlyphs to pass on Windows XP
  Finally, remove some trailing whitespace.
  Fix warning with gcc in -pedantic
  Make tst_image a little bit more tollerent to rounding errors
  Fix compilation with RVCT
  Test native graphics engine in tst_QGlyphs
  Remove unused function in tst_QGlyphs
  qdrawhelper:  optimize fetchTransformedBilinear
  qdrawhelper:  remove code duplication
  Fix maketestselftest by adding the qglyphs test
  add missing header
  make the plugin loader autotests pass
  Reimplement more of QAbstractItemModel in QAbstractProxyModel
  Qt now really unloads plugins and libraries when exiting an app
  Don't add the qmediaplayer.pro to the destination path of the sources.
  New class: QGlyphs

+/*!
+    \class QGlyphs
+    \brief the QGlyphs class provides direct access to the internal glyphs in a font
+    \since 4.8
+
+    \ingroup text
+    \mainclass
+
+    When Qt displays a string of text encoded in Unicode, it will first convert the Unicode points
+    into a list of glyph indexes and a list of positions based on one or more fonts. The Unicode
+    representation of the text and the QFont object will in this case serve as a convenient
+    abstraction that hides the details of what actually takes place when displaying the text
+    on-screen. For instance, by the time the text actually reaches the screen, it may be represented
+    by a set of fonts in addition to the one specified by the user, e.g. in case the originally
+    selected font did not support all the writing systems contained in the text.
+
+    Under certain circumstances, it can be useful as an application developer to have more low-level
+    control over which glyphs in a specific font are drawn to the screen. This could for instance
+    be the case in applications that use an external font engine and text shaper together with Qt.
+    QGlyphs provides an interface to the raw data needed to get text on the screen. It
+    contains a list of glyph indexes, a position for each glyph and a font.
+
+    It is the user's responsibility to ensure that the selected font actually contains the
+    provided glyph indexes.
+
+    QTextLayout::glyphs() can be used to convert unicode encoded text into a list of QGlyphs
+    objects, and QPainter::drawGlyphs() can be used to draw the glyphs.
