Method ScaleAllSizes

imgui_tiny_app/imgui/imgui.cpp:1577–1627

Scale all spacing/padding/thickness values. Do not scale fonts. Important: This operation is lossy because we round all sizes to integer. If you need to change your scale multiples, call this over a freshly initialized ImGuiStyle structure rather than scaling multiple times.
