Doh, I mistoke "Close and comment" for "close form" :D |

Did you make any comment? I can't see anything... |

Because I deleted it, I was going to ask how you make that fancy checkbox, but then I realized I can just press edit and see... Sorry for the noise! |

lol |

It probably isn't working with Qt because the OpenGL context doesn't get created (I don't think) until the window is shown. Try showing the window, then hiding it, hopefully it works. That should work with all backends. Actually, it might not because we can't guarantee that the canvas is actually ready to paint without doing |

Leaving the Qt bug to a future PR -- this is ready for review/merge. Putting this in the v0.3 milestone as well. |

LGTM, +1 for merge. |

Ready for review but not for merging:
we should make it work with any backend (only tested with glfw, doesn't work with Qt yet)(for another PR...)In another PR, we could create an easy utility routine to simplify offscreen rendering (i.e. automatic creation of FBO, screenshot, etc.).
