Subject: darwin: Add Foundation conversion functions for QSize/QSizeF
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The fromCGPoint function was left out for QSize, as the foundation type is
using CGFloats internally. Clients should use an explicit QSizeF::toSize()
when potentially throwing away precision.
