GtkSharp/generator/BoxedGen.cs
Dan Winship 622c360576 * parser/gapi2xml.pl (addFuncElems): if a struct or boxed type has
a constructor or a ref, unref, or destroy method, then it must be
	a reference type, so mark it "opaque" but then also mark all of
	its fields public and writable.

	* */*-api*.raw: Regen

	* generator/Parser.cs (ParseNamespace): make the opaque attribute
	check actually look at the value of the attribute rather than just
	checking if it's there, so that you can change a struct's opaque
	attribute from "true" to "false" via metadata and have that work.

	* generator/BoxedGen.cs (Generate): do not generate the boxed's
	"Free" method (since it's guaranteed to crash when we pass it a
	stack pointer). If "Copy" is marked deprecated, create a
	deprecated no-op for it, otherwise just skip it (since otherwise
	it will just leak memory when we copy its result onto the stack).

	* pango/Pango.metadata: deprecate Pango.Color.Copy and
	Pango.Matrix.Copy. Hide some array fields in Pango.GlyphString
	that we've never generated correctly. Tweak Pango.LayoutLine
	fields to be the same as they used to be.

	* pango/GlyphItem.custom (glyphs, item):
	* pango/GlyphString.custom (Zero, New):
	* pango/Item.custom (Zero, New):
	* pango/LayoutRun.custom (glyphs, item): add deprecated API compat

	* gdk/Gdk.metadata: undo the parser's new opaquification of
	Gdk.Font; it's been deprecated since pre-gtk# times, and no one
	should be using it, so there's no point in fixing it now. Fix up a
	few other things to match how they used to be. Fix RgbCmap's
	constructor args.

	* gdk/RgbCmap.custom (Zero, New): deprecated API compat

	* gdk/PangoAttrEmbossed.custom:
	* gdk/PangoAttrStipple.custom (Zero, New, Attr): deprecated API
	compat
	(explicit operator ...): allow casting back and forth between
	Pango.Attribute. (We can't usefully make them real subclasses of
	Pango.Attribute, because there's no way for
	Pango.Attribute.GetAttribute() to be able to dtrt with them.)

	* gtk/Gtk.metadata: deprecate Gtk.Requisition.Copy,
	Gtk.TextIter.Copy, and Gtk.TreeIter.Copy. Mark the return value of
	TextView.DefaultAttributes as "owned". Mark TargetList's fields
	private so it stays how it used to be.

	* gtk/TextAttributes.custom (Zero, New): deprecated API compat

	* gnomevfs/Gnomevfs.metadata: remove a bunch of opaque
	declarations that the parser figures out on its own now.

	* art/Art.metadata:
	* glade/Glade.metadata:
	* rsvg/Rsvg.metadata: un-mark everything the parser marked opaque
	in these libraries, because all of the structs in question would
	still be unusably broken, so the API churn would be pointless.
