We must be carefull in general.  Speed is an issue, especially with Windows.
If all programs forego the ability to use the 'Extra Bytes', too much
time CPU will be used in the GetProp function.  The GetWindowWord and Long
routines are significantly faster than GetProp.  Some programs use
these capabilities to store object pointers.  In order to retrieve the
object during a Window Message, you gotta call one of them.  As the
number of programs in the desktop increase, so will the number of
messages and speed will become an issue.  This hasn't happened yet,
but programmers should think along this line.
