gratuitous differences from the C version. Make comment and indent
	style consistent. Don't use "this." where not needed. Override
	OnDeleteEvent rather than connecting one's own DeleteEvent signal.

	* sample/GtkDemo/DemoApplicationWindow.cs (static
	DemoApplicationWindow): register the Gtk logo icon with
	StockManager so it shows up correctly in the toolbar.
	(AddActions): Register the radio items as radio items so they work
	right.

	* sample/GtkDemo/DemoHyperText.cs (EventAfter): handle
	link-clicking from Widget.WidgetEventAfter (as in the C version),
	rather than ButtonRelease, now that WidgetEventAfter is wrapped.

	* sample/GtkDemo/DemoImages.cs (DemoImages): use
	Gtk.Image.LoadFromResource (particularly to make the animation
	work right).
	(OnDestroyed): handle clean up (remove the timeout, etc)

	* sample/GtkDemo/DemoMain.cs (LoadStream): Fix handling of blank
	lines and whitespace to match the C version.

	* sample/GtkDemo/DemoPixbuf.cs (Expose): Use
	System.Runtime.InteropServices.Marshal.Copy() to copy
	pixbuf.Pixels to pass to DrawRgbImageDithalign, to make this more
	like the C version (and probably faster?)
	(timeout): Remove the FIXME since it seems to work now

	* sample/GtkDemo/DemoStockBrowser.cs: Simplify a bunch. Use
	reflection to get the C# names of the stock icons rather than
	trying to correctly re-mangle the ids. Display the Label with the
	accelerator underlined.

	* sample/GtkDemo/DemoTextView.cs (AttachWidgets): use
	Gtk.Image.LoadFromResource, so the image is properly loaded as an
	animation, not a static image. Don't set the combobox's "Active"
	property (for consistency with the C version).
	(InsertText): Fix miscellaneous differences with the C version.
	Remove some leftover cruft from earlier workarounds for gtk# bugs.

	* sample/GtkDemo/DemoTreeStore.cs (AddColumns): Make this more
	like the C version so the checkboxes are sensitized and hidden
	correctly on a per-row basis.

	* sample/GtkDemo/DemoUIManager.cs: Make the radio menu items work.

This port of gtk-demo.c is still INCOMPLETE. If you can contribute to it
don't hesitate to mail your patches to gtk-sharp-list@lists.ximian.com
This is a mostly complete port of gtk-demo to Gtk#; for notes on
what's missing, see the TODO file.
The original port was done by Daniel Kornhauser (dkor@alum.mit.edu),
with additions/changes/fixes by various other people, as seen in the
main gtk-sharp ChangeLog.
To compile it just type Make
Daniel Kornhauser.
For the most part, the various demos should stay as close as possible
to the C version, so that GtkDemo.exe can be compared against gtk-demo
to make sure Gtk# is working correctly.

General
- general C#-ification
- gtk-demo passes a widget to each demo that is used to set the
Screen and sometimes Parent of each demo window
- Demo window management is not the same as in gtk-demo
DemoMain
- syntax highlighting
DemoStockBrowser
- underline _label properly
- use StudlyCaps instead of current horrible hack
- missing stockitems for some reason
- remove duplication in ListStore, and use DataFunc's
DemoHyperText
- link tags are recreated too much and never removed
"Change Display" is missing
Future
------
IconView - gtk 2.6
RotatedText - pango 1.6
