Merge pull request imgui-rs#171 from malikolivier/patch-use-support-g…

…lutin-exclude-examples

Use imgui-glutin-support in examples and split examples [use "exclude" Cargo.toml feature]

This implement the suggestions discussed in imgui-rs#163 and imgui-rs#168.

- Use imgui-glutin-support crate in all examples.
- Exclude examples from the main workspace to prevent glutin version conflicts
- Allow setting HIDPI factor to imgui-glutin-support crate for current examples to work on all platform.

Then, I committed a working Cargo.lock for the examples so that the correct version of glutin be selected in all cases.
