I remember looking at this and thinking that it's entirely un-necessary
since a window will _never_ return #$wInGrow unless it has a grow icon
anyways, why have a check to see if the window has a grow icon? what
should really be happening here is a call to a customizable method
called, say, handle-grow-click, or track-grow-select that, by default,
handles clicks in the grow region in a default way, but allows users
to customize that behavoir easily.

if anywhere, this should be a :before or :after method for updating
the content area of windows of type documentProc, since that is the
_only_ place where it makes any sense for it to appear--afterall, you
are drawing into the contents of the window when you ask for the
grow icon to be drawn. As well, this doesn't need to be done for all
windows that have grow regions--wdef's will only draw a grow icon
if the grow icon is in the content area--some wdef's draw their grow
region in their struct region.
