/**
* This class provides a custom Size_ cursor which can be rotated
* to adjust with the rotation of a frame.
*
* It maintains a database of pre-rotated cursors so user is not
* expected to cache cursors.
*
* It provides a cast operator to QCursor& so you can use it directly
* where reference to QCursor are required.
* example:
* QApplication::setOverrideCursor(ScResizeCursor(19.76));
*
* Note that rotation is rounded (with qRound()) in order to save memory usage.
