Params: none
Returns: Returns the default Font(or Pango Font Description if using PANGO)
For Text/Font Routines: if the Font is invalid, this can be used instead, or
if the DT_internal flag is used(aka use system font) this is used. This is
also the font returned by GetStockObject(SYSTEM_FONT).
It attempts to get the font from the default Style, or if none is available,
a new style(aka try and get GTK builtin values), if that fails tries to get
a generic fixed font, if THAT fails, it gets whatever font is available.
If the result is not nil it MUST be GDK_FONT_UNREF'd when done.

fixes for gtk2
added more wrappers for gtk1/gtk2 converstion and sanity
removed pointless version $Ifdef GTK2 etc
IDE now "runs" Tcontrol drawing/using problems
renders it unuseable however
Revision 1.197 2003/09/06 17:24:52 ajgenius
gtk2 changes for pixmap, getcursorpos, mouse events workaround

Revision 1.194 2003/09/05 18:19:54 ajgenius
Make GTK2 "compile". linking fails still
(Makefile.fpc needs pkgconfig libs/GTK2 linking rules,
but not sure how not sure how) and when linked via a make script
(like gtk2 examples do) apps still won't work(yet). I think we
need to do a lot of work to make sure incompatible(also to get rid
of deprecated) things are done in GTK2 interface itself, and just
use more $Ifdef GTK1 in the gtk interface itself.

Patch includes:

-temporarily fixes TCustomForm.BorderStyle in bsNone
-temporarily fixes problems with improper tabbing in TSynEdit
Revision 1.104 2002/09/27 20:52:24 lazarus
MWE: Applied patch from "Andrew Johnson" <aj_genius@hotmail.com>
Here is the run down of what it includes -
-Vasily Volchenko's Updated Russian Localizations
-improvements to GTK Styles/SysColors
-initial GTK Palette code - (untested, and for now useless)
-Hint Windows and Modal dialogs now try to stay transient to
the main program form, aka they stay on top of the main form
and usually minimize/maximize with it.
-fixes to Form BorderStyle code(tool windows needed a border)
-fixes DrawFrameControl DFCS_BUTTONPUSH to match Win32 better
when flat
-fixes DrawFrameControl DFCS_BUTTONCHECK to match Win32 better
and to match GTK theme better. It works most of the time now,
but some themes, noteably Default, don't work.
-fixes bug in Bitmap code which broke compiling in NoGDKPixbuf
mode.
-misc other cleanups/ fixes in gtk interface
-speedbutton's should now draw correctly when flat in Win32
-I have included an experimental new CheckBox(disabled by
default) which has initial support for cbGrayed(Tri-State),
and WordWrap, and misc other improvements. It is not done, it
is mostly a quick hack to test DrawFrameControl
DFCS_BUTTONCHECK, however it offers many improvements which
can be seen in cbsCheck/cbsCrissCross (aka non-themed) state.
-fixes Message Dialogs to more accurately determine
button Spacing/Size, and Label Spacing/Size based on current
System font.
-fixes MessageDlgPos, & ShowMessagePos in Dialogs
-adds InputQuery & InputBox to Dialogs
-re-arranges & somewhat re-designs Control Tabbing, it now
partially works - wrapping around doesn't work, and
subcontrols(Panels & Children, etc) don't work. TabOrder now
works to an extent. I am not sure what is wrong with my code,
based on my other tests at least wrapping and TabOrder SHOULD
work properly, but.. Anyone want to try and fix?
-SynEdit(Code Editor) now changes mouse cursor to match
position(aka over scrollbar/gutter vs over text edit)
-adds a TRegion property to Graphics.pp, and Canvas. Once I
figure out how to handle complex regions(aka polygons) data
properly I will add Region functions to the canvas itself
(SetClipRect, intersectClipRect etc.)
-BitBtn now has a Stored flag on Glyph so it doesn't store to
lfm/lrs if Glyph is Empty, or if Glyph is not bkCustom(aka
bkOk, bkCancel, etc.) This should fix most crashes with older
GDKPixbuf libs.
