From Valeriy Onuchin:
- TGPictureButton - AddReference for pic asigned as disabled picture
- TGImageMap - set disabled picture the same as a normal picture.
That fixes "disabled" appearence of TGImageMap (see, for example, WoldMap.C tutorial)

From Valeriy Onuchin:
- new concept of "pseudo-window" introduced.
pseudo-window - is an object inherited from TGWindow which
is not created by window system (X11 or M$ Windows).
It does not consume window system resouces.
The main use-case of pseudo-windows is GUI containers
with very large number of items. For example, listviews, listboxes,
where listview/listbox items/entries are pseudo-windows.
Pseudo-window has "window id" equal to zero.
In order to "activate pseudo-window concept" the parent should
have fIsMapSubwindows dat member to be kFALSE.
So, it's backward compatible, setting fIsMapSubwindows=kTRUE in parent window
will activate normal behavior, i.e. will be created in window system.
Introduction of "pseudo-window concept" forced the changes in
TGX11, TGWin32 classes to avoid TVirtualX methods execution when
"window id" is NULL (the case of pseudo-window).
Introduction of pseudo-windows which do not consume window system resouces
greately improved performance of TGListView, TGListBox, TGComboBox objects.
Now it's possible to have these containers with more than 10000 items.
- some optimization in TGLBContainer drawing
- add SetWindowName to most GUI classes. It's very usefull for GUI debugging.
