Hi Sandro, I'm torn on whether to fallback to using the DisplaySettings:instance() when DisplaySettings isn't explicitly specified. Defaulting to using DisplaySettings::instance() has the advantage of forcing a particular graphics context version and other parameters from one place. Conversely it could be a real issue for some applications that assume that the values will just be straight defaults without picking anything else up implicitly - we could inadvertently break their applications. These changes in behaviour could be quite difficult to trace as the application would just compile and link as before, but now has different behaviour.
Given this I we'll need to be really careful about making the default. I don't yet have any clear direction on it. Will need to think some more. Robert.
