Potentially all these IDisposable classes could be used after being
disposed, which would result in native crashes. We now do an explicit
check and throw an exception in managed land when the object has been
disposed.
This is particularly useful because:
a/ the native crashes are quite obscure, there no indication that
you're using a disposed object
b/ Gtk# is passing Context instances to user methods, and disposes them
when the method returns. So if the user code keeps a reference to the
Context, there a good chance it will try to use it after it's disposed.
Other changes in this patch include:
* Renaming a parameter to be more consistent with the other subsequent
ctor called.
* Replacing implementation of some [Obsolete()] methods with the call
to the methods they were replaced with, to avoid redundancy and the
need for more CheckDisposed() calls than necessary.
* Throw ArgumentException when receiving an IntPtr.Zero as a handle,
as a way to protect ourselves from wrapping invalid native pointers,
and throwing ObjectDisposedExceptions because the object was invalid in
the first place.

When the finalizer calls Dispose(), disposing is false, it means that
CairoDebug traces should be printed, but the reference count on the
native context should still be decreased. Otherwise a real leak
would appear, as the native context would never be freed when the
managed object is GCed.
Also:
* improving naming consistency
* obsolete old/broken stuff
* clean up tabs/space mix
NOTE: this removes the wrapper caches for Pattern and Surface as
there was no reliable way to clear them.
This is a merge from changes in Mono.Cairo in mono 3.2.
The third and fourth parameters of the Rectangle constructor are width
and height, but cairo_stroke_extents and cairo_fill_extents give right
and bottom coordinates.

Cairo has a different API version that was hardcoded. Define it in a new
variable in configure.ac and use it in AssemblyInfo and Makefile.am.
This fixes make distcheck, as the cairo-sharp.dll assembly was not
getting uninstalled from the GAC.
* cairo/Context.cs: add ctor (IntPtr, bool owned)
* cairo/cairo-api.xml: expose cairo_t as new ownable symbol type
* generator/HandleBase.cs: implement IOwnable
* generator/IOwnable.cs: new interface for wrapping ownable types
* generator/Makefile.am: add new files to build
* generator/OwnableGen.cs: SimpleBase subclass to expose IOwnable
* generator/Parameters.cs: use IOwnable.FromNative instead of HandleBase
* generator/Parser.cs: parse ownable symbol type
* generator/ReturnValue.cs: use IOwnable.FromNative instead of HandleBase
* cairo/Context.cs: use Pattern.Handle
* cairo/Pattern.cs: expose Lookup method, Obsolete the Pointer prop and
add a new Handle prop for API consistency.
* cairo/cairo-api.xml: add Pattern symbol.
* cairo/*: merge changes to Mono.Cairo since we split back in Oct 2008.
Not much changed. Scrubbed the doc index and updated NativeMethods
to match. Commented with DONTCARE the ones we will ignore. Implemented
a few of them, including an initial Device binding. Still some work
to do, and some discovery to be done to see what happened to Xcb, Glitz,
and DirectFB surfaces and whether we need to remove those classes.
* cairo/cairo-api.xml: add the Content enum type and fix surface symbol.
* gdk/gdk-sharp.dll.config.in: s/3.0/3/ on the so name.
* sample/Makefile.am: enable scribble.exe build
* sample/Scribble.cs: rewrite for new API, specifically replace pixmap
drawing usage with cairo, and use OnDrawn in place of OnExposeEvent.
Also Made it a subclass of DrawingArea instead of handling events.
* cairo/Surface.cs: expose LookupSurface
* cairo/cairo-api.xml: add surface mapping
* gdk/*: updates and hobbling to get gdk building. lots of work
to come.
* configure.ac: drop cairo conditionality
* cairo/AssemblyInfo.cs: set version to 1.10.0.0
* cairo/Makefile.am: unconditional build and add Region.cs
* cairo/cairo-api.xml: initial type exposure.
* pango/Makefile.am: use cairo-sharp.dll and cairo-api.xml
* pango/Pango.metadata: drop explicit symbol additions.
* gdk/Gdk.metadata: drop explicit symbol additions.
* gdk/Makefile.am: use cairo-sharp.dll and cairo-api.xml
* gtk/Makefile.am: use cairo-sharp.dll and cairo-api.xml
* sample/Makefile.am: use cairo-sharp.dll
* sample/GtkDemo/Makefile.am: use cairo-sharp.dll
This is an initial stab at a 1.10 binding. It will probably take
more based on the number of errors still coming out of the Gdk
build.
* AssemblyInfo.cs.in: kill keyfile attr
* Makefile.am: moved mono.snk to cairo dir
* Makefile.include: no need to copy snk into builddir any longer.
* cairo/AssemblyInfo.cs: kill keyfile attr
* cairo/Makefile.am: snk relocated into here. use it directly.
* glib/Makefile.am: no need to copy snk into builddir any longer.
* gtkdotnet/Makefile.am: no need to copy snk into builddir any longer.
* */Makefile.am: standardize on - options over / options for
consistency. Also assists with build on msys. [Fixes#550667]
svn path=/trunk/gtk-sharp/; revision=147125
* configure.in.in: Target .net 2.0 profile
* gapi-cdecl-insert: Kill. We are now using the UnmanagedFunctionPointerAttribute
for callbacks.
* glib/CdeclCallback: Mark obsolete.
* generator/*.cs:
* *.custom: Use [UnmanagedFunctionPointer (CallingConvention.Cdecl)] instead of
[GLib.CDeclCallback].
svn path=/trunk/gtk-sharp/; revision=137323
* cairo/Makefile.am: use mono.snk to sign the Mono.Cairo assembly
so that it's compatible with mono built versions. Initial patch
from Christian Hoff with a few tweaks.
svn path=/trunk/gtk-sharp/; revision=122821
* configure.in.in: magic for local Mono.Cairo build.
* cairo/*: a local build of Mono.Cairo for .Net-only builds on win32.
* */Makefile.am: use local Mono.Cairo where necessary.
svn path=/trunk/gtk-sharp/; revision=115399
