> DateField.measure() has two problems:
> 1. It is a few pixels too small, causing the text field inside it to scroll.
> To reproduce:
> * Create an editable DateField <mx:DateField editable="true" />.
> * Choose a date (say, 01/01/2009).
> * Click somewhere else to move the focus out
> * Click in the DateField again, at the end (to the right of the "9")
> Result: the start of the date "scrolls" away
> Fix: make it 4 pixels wider (in DateField.measure, add an extra "+4" to the
> "measuredMinWidth = measuredWidth = ..."
> 2. It tries to use 31/12/2004 as a sample date to measure the width, but it
> does new Date(2004, 12, 31), and months are 0-based there, so it actually
> uses 31/01/2005. With a date format where the month can be shown as 1
> character, this causes the DateField to be one character too small.
> This can be reproduced in Flex 3.2 by having a labelFunction that formats the
> date like that, or (didn't test) since SDK-15386 the DateField itself also
> supports formatStrings like D/M/YY.
> Fix: replace it by new Date(2004, 11, 31)
> Workaround for both: override DateField.measure in a subclass, copying the
> implementation but adding an extra +4 and fixing the month in the date.
