   thus constant (by nature) function modifies object's state. This makes it impossible
   to paint the same widget twice by calling DoRedraw, the second time exposed region is empty.
   This does not work with cocoa.
2. CreateFontCollection for a specific name always finds only 1 font, not all variations of the same font,
   instead I have to request the full list every time and filter it myself.
3. TGFontDialog: connects signal/slot only for gVirtualX inherited from TGX11 (or TGX11 itself),
   must also work for TGCocoa. all_sizes and all_styles variables also were set incorrectly for TGCocoa
   (initialization uses check InheritsFrom("TGX11")).

Fix to prevent a potential crash when deleting canvas with toolbar, as reported on the forum (http://root.cern.ch/phpBB3//viewtopic.php?f=3&t=14627)

color wheel object creates a canvas (step 1), appends itself 
into this canvas (step 2). This code relies on the fact, that
all events (configure/expose/etc) will be received _after_ step 2
and canvas will be eventually repainted later. This is not true in case
of cocoa: window is created and made visible on step 1, it's repainted
after step 1 and before step 2, so any contents added after step 2
will become visible only after gPad->Update() call (BTW, this is how it's 
done in TRootCanvas for "View"->"Markers".

Call gPad->Update(), do not rely on X11 specific (events in a queue at the end
of event loop iteration).

it crashes - parses this XLFD, sets foundry to 0 and later use strcasecmp on this pointer.
1. 'Fix' TGFontPool not to use 0 pointers,
2. return fake foundry.

TGView frame (base of TGTextView) has a child window - TGViewFrame.
TGViewFrame is never actually painted (DoRedraw never gets called for this window),
but ... it receives Expose event and delegates it to ... its parent - TGTextView,
and TGTextView, it its DoRedraw (or DrawRegion) .... tries to paint into child window - TGViewFrame.
While this is may be OK for X11 or Window, with Cocoa it's a total mess and disaster - if some view is
to be updated, it does not expect a child to be suddenly rendered in the middle of work.

View is not a window.

I've added some quite risky code to address this problem (text scrolling is still wrong) - only 
"static rendering" for a text view works now.

This is noop for windows/X11, but needed on MacOSX to let
gVirtualX know, that nested loop for some specific window started -
to make it impossible for AppKit to bring other window to the front and 
overlap and hide window which we are waiting for.

Fix a weird behavior in combo boxes: When the mouse button was pressed on the scrollbar of the combobox popup, and then released outside, the "dragging" flag was not released, and the scrollbar element was following the mouse move events (as if it was grabbed). Thanks Timur for pointing out this oddity.
