This would fix the weird behavior I've described in #68.
I really don't know if this is a proper fix, but it works with Wolf Shaper and the rectangles example I've shown in the issue.
It makes the subwidgets pass through this OpenGL code, which sets the correct viewport:
DPF/dgl/src/WidgetPrivateData.hpp
Lines 81 to 88 in 6d35b69
So, calling
rect(0, 0, getWidth(), getHeight());
should draw a rectangle equal to the widget's viewport.Also, in onNanoDisplay(), you can freely use NanoVG's translate(), reset(), etc. It doesn't seem to affect the OpenGL viewport.
