We now support -gtk-win32-theme-part(class,part,state) in background
and border-image CSS properties. This renders the corresponding
theme part using DrawThemeBackground() and acts as a base for a
CSS based windows theme.
Note that we build the parsing code even on non-win32 so that
all themese will parse the same on all arches. We draw pink instead
of the actual theme parts on non-win32 though.
At the toplevel we have _gtk_theming_engine_get, which lets us pass
in a property context with (atm) the size to get the property for.
Then there is a lot of plumbing to push this down into the lower
layers of the style property code until finally hitting
the property resolvers.
I need this because I will be adding a property resolver for win32
theme parts, and they render differently depending on the size
(i.e. they don't scale linearly). The idea is that the code
to get the background properties will pass in the final size
and we will resolve the theme part specification to that particular
size.
If the old non-context calls are used we just hardcode a size
of 100x100.
We used to special handle gradient, but we want to be able to store
other sources (that will eventually resolve to cairo patterns).
For instance, this is needed to handle win32 theme part sources.
By default, a background image is stretched. Instead, it is worth to
have a tiled background.
This patch allows background surfaces to be repeated or not, and should
be compatible with future extensions and CSS.

gtk/gtkborderimage.c, gtk/gtklabel.c and gtk/gtkstyleproperty.c call
round() and/or rint(), which was only available in C99 compilers.
This adds the inclusion of the fallback implementation (gtk/fallback-c89.c)
to define these functions if they are not initially made available by the
compiler.
Also remove the rint() implementation in gtk/gtklabel.c as it is now in
the fallback implmentation.
... and implement the CSS font properties:
- font-size
- font-style
- font-family
- font-weight
- font-variant
This is the second try at this. The first was backed out previously due
to bugginess. Let's hope this one survives a bit longer.
Also makes the font-family CSS test work again.
This is necessary because we want to use NULL as the default value. But
the default value for borders is { 0, 0, 0, 0 } and not NULL.
Fixes border-image-gradient and border-image-repeat reftests.
It's useful to set a slice size != border-width, as backgrounds are
clipped to border-width too.
As slices can be half-transparent and overlap the background,
this would not fill the border box properly if we only use a single
property for specifying the width.
Also, this brings us even closer to CSS3.
It's a custom property with the same semantics of text-shadow, which
works on icons and icon-like UI elements, such as spinners, arrows and
separators.
It's composed by
- border-image-source: a cairo_pattern_t holding an image from file or a
gradient
- border-image-slice: a GtkBorder containing the slice offsets to apply
on the image
- border-image-repeat: a GtkRepeatType for the image
We deviate from pure CSS3 in the following ways:
* border-image-width is assumed to be always 1, i.e. always equal to
what's specified by border-width. I don't think it's a particularly
useful property to have, but we could add it later if needed.
* border-image-outset is absent, as we can't render outside of the
allocation yet.

The hack in gtk_style_context_get_font() was causing segfaults in
combobox code. This is not acceptable and I'm not awake enough to fix
it, so just reverting until it's fixed sanely is easiest.
This reverts commit cf6bfbdb17.
Inheritance is now done using style property flags, so thereis no ned
anymore to clobber the pspec flags namespace.
Also, there is no need to expose this functionality in the public API
without exposing more of the styleproperty API.
This essentially reverts commit 9bfd3d2eec.
