send keypress for modifiers

[carlfarrington]

I am trying to use the keyboard with FreeRDP client, wayland version (wlfreerdp).
I have put the keyboard in the OVERLAY layer so that it shows on top of full screen wlfreerdp.

It almost works perfectly, but none of the modifier keys are detected. All I get is lowercase letters.

When comparing to a physical keyboard, the difference I can see (on the FreeRDP side) is that the modifiers (shift, ctrl, alt), are actually detected as keypresses, as well as modifier data.

Would it be straightforward to have the modifier keys come through as keypresses ?

I managed to do this, but it's probably not good enough for a pull request. It is perfect for my needs though
I'll leave the fork available in case it's of use to anybody else.
