Deleting OpenGL windows with the new Cocoa Mac version leads to crashes.
To trigger the issue:
- compile the small example (fltk-config --use-gl --compile gldelete.cpp)
- run the code and press 'd' (this should delete the OpenGL window, then
recreate a new one)
On my machine the code crashes with the new Cocoa version. It works fine
with fltk 1.1 (Carbon).

// compile with "fltk-config --use-gl --compile gldelete.cpp"

// run code, then press 'd'
// - expected behaviour: the opengl window is deleted and replaced
// with a new one
// - observed behaviour: code crashes
