ImGui binding: weird constants for key bindings

[BrunoLevy]

Some number keys (first row, not keypad) have weird ids
(reported by @gloook). Use attached Lua code to display them:

-- Lua (keep this comment, it is an indication for editor's 'run' command)

glo_dialog = {}
glo_dialog.visible = true
glo_dialog.name = 'glo_dialog'
glo_dialog.x ,glo_dialog.y = 200,600

function glo_dialog.draw_window()
  imgui.Text("GLO")
  for i=530,600 do
    if imgui.IsKeyDown(i) then
      print(i)
    end
  end
end

graphite_main_window.add_module(glo_dialog)

Normally, keys 0..9 are mapped to [536..545], with symbolic constants ImGuiKey_0..ImGuiKey_9, but two keys have different constants:

• 4 -> 596 (instead of 540), which means ' (4 without shift)
• 6 -> 598 (instead of 542), which means - (6 without shift)

I think it is a bug in ImGui / french keyboards.

Workaround:

Test for 4:

if imgui.IsKeyDown(ImGuiKey_LeftShift) and  imgui.IsKeyDown( ImGuiKey_Apostrophe) then
...
end

Test for 6:

if imgui.IsKeyDown(ImGuiKey_LeftShift) and  imgui.IsKeyDown( ImGuiKey_Minus) then
...
end
