There is a pending patch to reinstate this for Qt 5.1 (the patch
introduces new API top QOpenGLContext). I will fold the revert of this
patch into:
https://codereview.qt-project.org/#change,31231
Note that QGLShaderProgram still supports Geometry shaders so source
compatibility with Qt 4.8 is maintained.

This corrects the mismatch between using floats for internal storage
and qreal in the API of QVector*D which leads to lots of implicit
casts between double and float.
This change also stops users from being surprised by the loss of
precision when using these classes on desktop platforms and removes
the need for the private constructors taking a dummy int as the final
argument.
The QMatrix4x4 and QQuaternion classes have been changed to use float
for their internal storage since these are meant to be used in
conjunction with the QVector*D classes. This is to prevent unexpected
loss of precision and to improve performance.
The on-disk format has also been changed from double to float thereby
reducing the storage required when streaming vectors and matrices. This
is potentially a large saving when working with complex 3D meshes etc.
This also has a significant performance improvement when passing
matrices to QOpenGLShaderProgram (and QGLShaderProgram) as we no
longer have to iterate and convert the data to floats. This is
an operation that could easily be needed many times per frame.
This change also opens the door for further optimisations of these
classes to be implemented by using SIMD intrinsics.
This needs to be applied in conjunction with

Primary goal, make the front page of the Qt GUI module a bit more

This change prevents the qWarning() in QOpenGLFunctions from being
triggered when creating a QOpenGLShaderProgram object without a current
QOpenGLContext. This is a common case especially when the shader program
is a member variable of a class.
It now relies upon the QOpenGLShaderProgram::init() function to resolve
the GL function pointers when the shader program is first used which of
course should be done with an active context.

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.
