QMatrix, QVector1-4D, QOpenGLShaderProgram let's make double precision please

Hello,

I would like to see implementation of QMatrix, QVectors and other things useable in QOpenGLShaderProgram to pass throught glUniform as double precision.

QMatrix, .. are currently float which is not great for beautiful graphics.

Here is screenshot from nvidia which showing difference between float and double in result: http://image.slidesharecdn.com/gtc2010opengl-100924140333-phpapp01/95/nvidias-opengl-functionality-46-728.jpg?cb=1285388123

I would like to see it in Qt 5.5, I think it's easy to implement, or is there possible way to do it myself? Basicly it's just changing all data types to double isn't it?

Thanks!
