[flexcoders] How to rotate a Combo Box

[wyattwang]

Here's the problem. 

After setting myComboBox.rotation = 270 the box itself can be rotated.
But the dropdown and textInput inside won't rotate.

By extending the mx:ComboBox, dropdown.rotation = 270 will work, but
the textInput.rotation = 270 does not work. Font Arial was embedded
into the application. How to make the textInput inside rotate to 270?
