Fix a misdeclared dependency in clim-listener.asd

asdf.lisp requires things from file-types.lisp.

Fall back to DejaVu instead of Vera, and fix serif italic filename.

It's not clear to me whether there used to be a serif oblique font which
has been superceded by the italic version, or whether the DejaVu filenames
have been broken since their inception and just were never fully tested.
Hopefully the latter.

• [DH] Experimental/freetype/xrender-fonts.lisp

Fixed a typo.

Thanks to Stas Boukarev.

• [DH] presentations.lisp

Fixed the font-selector demo so that it doesn't crash.  The problem
was that when the family changes, it tries to initialize the face to
one with the same name as the selected one in the old family.  When
there is no such face in the new family, it got initialized to nil.

However, the demo is still not working properly.  Sometimes a
displayed face becomes non-clickable, and sometimes two faces are
highlighted simultaneously.

• [DH] Examples/font-selector.lisp

Fixed a bug that made this demo not work (thanks to "lhz" on #lisp).

Improved the code somewhat to avoid too much code duplication.  It
could be made better still.  On the other hand, this demo should
probably be redone or removed, since it involves the calculator as
well, which doesn't seem reasonable.

• [DH] Examples/sliderdemo.lisp

Removed dead code.  Added my copyright.  Fixed some comments.

• [DH] Examples/traffic-lights.lisp

This file was old, and has been replaced by traffic-lights.lisp.

Faster IMAGE-TO-XIMAGE translator, courtesy of Nikodemus Siivola.

• [DH] Backends/CLX/medium.lisp

Fix dynamic extent declarations in with-output-as-gadget.

• [DH] gadgets.lisp

Fixed problem with Cancel button in accepting-values.

Thanks to Kilian Sprotte for the patch.

• [DH] dialog.lisp

Added support for image design drawing in the gtkairo backend.
Thanks to Samium Gromoff for contributing this patch.

• [DH] Backends/gtkairo/cairo.lisp
• [DH] Backends/gtkairo/ffi.lisp

Added support for reading PNG files contributed by Samium Gromoff.  Thanks!

FRAME-MANAGER-NOTIFY-USER
    Use :calling-frame, leave shareing the event queue to the calling
    frame to what ever magic does it correctly in that case.

• [DH] dialog.lisp

(ADOPT-FRAME :AFTER CLX-FRAME-MANAGER APPLICATION-FRAME)
    If the frame happens to have a non-null calling-frame slot, tell
    the window manager. That way pop up dialogs are recognized as such
    allowing the window manager to apply what ever special handling it
    does to pop up windows.

(ALLOCATE-SPACE SCROLLER-PANE T T)
    Missed one *SCROLLBAR-THICKNESS*

SCROLL-AREA
    Removed this ticking bomb.

• [DH] panes.lisp

I like my scroll bars left, Hefner wants them right. So I made it
tweakable. Default is right though.

CLIM-EXTENSIONS:*DEFAULT-VERTICAL-SCROLL-BAR-POSITION*
    New variable^Wparameter intented to be settable by the user.

VERTICAL-SCROLL-BAR-POSITION slot of SCROLLER-PANE
:VERTICAL-SCROLL-BAR-POSITION init arg of SCROLLER-PANE
    New.

(ALLOCATE-SPACE SCROLLER-PANE T T)
    Use it. Do not use *SCROLLBAR-THICKNESS*, but rely on the space
    requirements of the scroll bars.

Use force-output instead of finish-output as the latter implies
waiting for an answer from the display server, which is something
we really do not want to do.

Patch from Nikodemus Siivola fixing a problem with missing unquotes.

• [DH] recording.lisp

Removed some tabs at the request of Cyrus Harmon.

There are lots of tabs in McCLIM source code, so I don't think it is
practical to remove them all right away.  Perhaps take the advantage
when there are other modifications as well.

• [DH] stream-output.lisp

Patch from Nikodemus Siivola adding an :after method on
stream-finish-output for standard-extended-output-stream.
