40f2af665d gdkcairo: Bail if surface is in error
Don't try to paint onto an error surface. This happens for example when
gdk_cairo_set_source_pixbuf() is called with a pixbuf that is too big
for Cairo to handle.

ceeed1c48d Add internal gdk_cairo_region_from_clip helper
This extract the current cairo clip region if possible and
returns it as a cairo_region_T. It will be needed by later code.

112e74ed64 gdk: Allow calling gdk_cairo_surface_create_from_pixbuf with scale 0
The documentation explicitly states that 0 is an allowed value for using
the same scale as the window. This 0 value is also explicitly checked
down in the call chain and handled.

This reverts commit a7562dd38f.

I prefer to not confuse gtk-doc with doc comments for private

ab34c79896 Fix gdk_cairo_region_create_from_surface on big endian
gdk_cairo_region_create_from_surface doesn't work correctly on PPC.
This is most prominently seen with the GTK window resize grip, the
shape of which is mirrored every eight pixels horizontally.

At the same time, use an A1 surface for the resize grip shape to
eliminates an A8->A1 surface conversion.

97e6e9d212 API: Make gdk_cairo_create() take a GdkWindow
This is not strictly an API change as GdkDrawable is typedeffed to
GdkWindow, but it changes the header, so I'm marking it as such.
gdk_cairo_create() can only be used with windows these days, so it makes
sense to pass a window. With that, we can alseo remove the
set_cairo_clip() vfunc from GdkDrawable and implement it inside
gdkwindow.c.

65dde2f92f API: Remove gdk_cairo_reset_clip()

5a5f8081f0 Add GdkRGBA struct to supersede GdkColor
GdkRGBA is a boxed struct similar to GdkColor, with the difference
that it stores alpha information as well, and colors are stored in
[0..1] doubles, in the cairo spirit.

gdk_cairo_set_source_rgba() has been also added to allow easier handling
of this new type.

computes a surface's extents.

78018767ba Implement GdkRegion in terms of cairo_region_t
Only changes in headers: GdkRegion and GdkRectangle are typedeffed to
cairo_region_t and cairo_rectangle_int_t respectively. The region type
was opaque anyway so it doesn't matter and the rectangle types are
identical.
