Delphi does not have these elements, and, since they are usually not working

This is easily fixable ;-) But until now I didn't realize this breaks
code written for Delphi that checked for empty set or superset. I take
back my argument for handling them in other messages then. The LCL
implements GetKeyState anyway (although I'd prefer it was "pascalized"
to avoid bitmasks...)
Of course. There should be a way to check key locks state,
TShiftState is just not a good place for this.

The keyboard lock states (ssNumLock etc.) modify *keyboard* input
(WM_KEYUP/DOWN), but are not normally usable with *mouse* input
(WM_LBUTTONUP/DOWN). That's why mouse input also does not normally
distinguish between e.g. left and right CTRL or SHIFT key, because left
handed people will use the modifier keys at the right side, when
operating the mouse with the left hand.
I see no reason for adding them to TShiftState, they better belong to
GetAsyncKeyState etc.
