Avoid QImage copy in toTexture()
Desktop OpenGL has GL_UNPACK_ROW_LENGTH which we
can use use to specify the image row stride.
This removes the need to call QImage::copy(). On
a retina MacbBok pro this reduces toTexture's share
of the total run time by 1-4%. (on tests/manual/
qopenglwidget/openglwidget)
