Hi. Sonar!

Porting old code to 4.1 on a Mac, I've found the glDrawElements with GL_QUADS doesn't draw and generates error. Yes, I heard the quadrangles are deprectated long ago, but hoped it won't touch me ;-) Looking in web I've not found yet how to draw them with newer OpenGL? Just 2 triangles is not a way to go, at least I need “wireframe” too.
Have a workaround?

Thx
Tom
