Way to know if AntiAliasing is enabled

I’m developing an addon to draw plots (ofxGrafica) and I realized that horizontal and vertical lines do not look very nice when the AntiAliasing is enabled.

I would like to disable it temporally when I draw the axes and enable it back to the previous status. The problem is that ofPushStyle and ofPopStyle do not keep the antiAliasing status.

I would like to have a way to know which is the current antiAliasing to restore it later to that value. Is there a way to do it? Something like ofAntiAliasingIsEnabled() would be nice, or even better, to add the AntiAliasing property to ofPushStyle.
