Increase wxStaticText height in wxMSW to align its text with wxTextCtrl.

Increase wxStaticText height in wxMSW to align its text with wxTextCtrl.

The base lines of the text in wxTextCtrl and wxStaticText which were
themselves vertically aligned didn't align, the text in the latter was one
pixel too low. This seems to be happening because we don't give enough
vertical space to the native static control by default and so, while the text
wasn't truncated, it was positioned differently than usual.

Work around this problem by allocating two extra pixels to wxStaticText
height. While the exact explanation of the problem remains mysterious, this
hack does result in correct appearance which seems to be sufficiently
important to apply it.
