I also need an engine to draw 2d (and 3d later) primitives like you've 
described above. I have a couple of unfinished attempts to make 
something like it. My specific is ability to inspect the data using some 
treeview widget. I considered GTK and Qt (both pure Qt and Qml) and they 
were too complex to make such user interface. The most suitable variant 
for me was dear imgui, but now I'm replacing it by nuklear. Generally I 
have no complete solution to the problem, but I'd like to join efforts 
to create it.
