ImGUI IO assertion failure

[prybicki]

With the most recent versions of ImGUI and Magnum, ImGUI example crashes with the following message:

external/imgui/imgui.cpp:7707: void ImGui::ErrorCheckNewFrameSanityChecks(): Assertion `g.IO.KeyMap[n] >= -1 && g.IO.KeyMap[n] < ((int)(sizeof(g.IO.KeysDown) / sizeof(*(g.IO.KeysDown)))) && "io.KeyMap[] contains an out of bound value (need to be 0..511, or -1 for unmapped key)"' failed.

Perhaps it is related to this discussion?

Should be fixed by #89

Works for me, thank you very much!

This got properly fixed with #93, merged as c60149c.
