Is it possible to retrieve the 'current' graphics attributes used by Processing at runtime? In particular, any of the following:

rectMode
ellipseMode
strokeWeight
strokeJoin
strokeCap
smooth/noSmooth

I need this because I would like to be able to temporarily modify these attributes for specific drawing operations but then return them to their previous values.

I realise that I could create my own variables that stored the state of each and then called the relevant Processing method in response to these variables, but I just wanted to check I wasn't missing something.

On a similar theme is it possible to detect which of  P2D,P3D,OPENGL is currently set? I need this because some operations fail at run-time in certain modes (e.g. smooth() in P3D). This is slightly more complicated because Processing insists that size() is the first line of setup(), so initialising a variable at run-time with this value is more difficult.

Thanks.

println("rectMode: " + g.rectMode);
println("ellipseMode: " + g.ellipseMode);
println("strokeWeight: " + g.strokeWeight);
println("strokeJoin: " + g.strokeJoin);
println("strokeCap: " + g.strokeCap);
println("smooth: " + g.smooth);

Looks like it works...

While this is a question that only Ben can answer authoritatively, if I had to guess, the case will be that for the foreseeable future, g will continue to be exposed, however its use is not officially approved in the sense that a) bug reports relating to its use will not be very high priority, b) no efforts will be made to make it very easy, and c) if some compelling reason comes up in the future to limit access, that might happen.

However, the general approach up until now has been to leave most of this stuff accessible but undocumented for the handful of advanced users that know what to do with it, and I doubt that will change any time soon.
