Mouse click and scroll event support for git-bash/mintty on Windows

[ariker]

The demo looks correct in git-bash on Windows, however it does not respond to mouse movement, click, and scroll events. It would be helpful to extend the existing drivers or driver selection to take this scenario into account. While the platform check will show "Windows", git-bash supports the event types in the Linux driver instead.

It's possible that a more nuanced environment check and loading the Linux driver in that case may enable it to work as expected.
