Seems like the PropertySheet's Lable Providers
have very limited functionality. For example -
we are not able to change the color or font of a property value.
We need to have visual distinction between read-only
properties and the writeable ones. For example we woud like
the read-only properties to be grayed(like disabled).
In order to do that I have implemented our own
LabelProvider, which derives from SimpleLabelProvider.
This class has the following methods:

 getLabelImage(IVisualPart, Object);
 getLabelText(IVisualPart, Object);

So, I was hoping that the VisualPart argument is actually
the table item/widget itself and I'll be able to change
it's appearance(for example it's color or font).

Unfortunately the PropertySheetViewer when updates the table
items, passes as first argument reference to itself instead to the TreeItem:
Follows excerpt from the PropertySheet code:

/*PropertySheetViewer  method*/
private void updateValue(TableTreeItem item)
{
   ...
   provider = getLabelProvider();

   String label = provider.getLabelText(this, entry);
   IImage image = provider.getLabelImage(this, entry);
   ....
}

But even if the PropertySheetViewer was passing the
TableTreeItem as first argument, that still wouldn't work,
because TableTreeItem doesn't have the needed functionality.

So, is there anything else we could do to change the color
or the font of a PropertySheet item's text?

	As stated above there is no way to do this since it is not supported by 
SWT.
	If this were considered important and SWT implemented the functionality 
	then we could find a way to provide this in the property sheet.

From what I can tell, they would like to be able to set the Color and/or Font 
of a single item in a TableTree.  
Correct me if I am wrong.
This is not available in the TableTree because it is not available in the Table 
(TableTree is just cake for a Table).  
This functionality is not available on the Table because Windows does not 
provide the API to do this. (I am 90% 
sure that this last statement is true and I will verify with Steve when he gets 
in).
I think this would require something like Owner Draw or implementing our own 
widget - both answers are a lot of work.

	Moving to SWT for consideration.

The information is:
	This is definitely an important functionality for us in the properties 
view.  
	Without this, the user cannot tell which properties are writeable, and 
which are read-only.
 
	If we cannot make this happen we need to let them know.

	What is required to fix this PR is to write our own TableTree widget 
(not use the native Table widget).

	This can be considered under the Custom Widget work but it clearly is 
going to require a bit of time 
	and needs to be prioritized relative to the other CustomWidgets.

	Can be addressed by a Custom Widget.
