[Interest] Enable sample buffers / samples on QGLWidget from Python

[Elvis Stansvik]

Hi all,

Sorry if this is slightly off-topic.

I'm working with a QGLWidget-based widget. I know it's deprecated, but
I'm tied to it for the moment since I'm working with VTK (something
QOpenGLWidget-based will come eventually..).

I have a need to enable sample buffers and set the number of samples,
to enable anti-aliasing.

I thought I could do (self is the QGLWidget):

glFormat = self.format()
glFormat.setSampleBuffers(True)
glFormat.setSamples(8)
self.setFormat(glFormat)

But realize now that setFormat has been made obsolete in Qt 5, and
PyQt as a policy does not wrap obsolete stuff.

Am I screwed or is there some other way to do this?

Thanks for any help,
Elvis
