4f9ea5e54b css: Use multiple font-family values
Pango API to support this, so we can implement
this very easily.

6ff326a82f css: Add a workaround for gtk_widget_override_font()
The problem here is that the CSS machinery expects font sizes to be in
pixels, but gtk_widget_override_font() provides a value in point and the
CSS machinery has no ability to query the DPI and convert.

This patch changes the dconversion DPI we use from a hardcoded 96 to the
default screen's DPI, which should work better than before.
This will of course not listen to changes in the default screen's DPI,
but that shouldn't be a problem.

People who want to workaround this should use gtk_widget_override_font()
with a font that has an absolute size set via
pango_font_description_set_absolute_size (size * PANGO_SCALE *
                                          gdk_screen_get_resolution (screen));

2603011ea0 Fix a typo
We don't want to parse a weight twice, but a weight and a stretch.

68ce676498 Add backwards compat back
Apparently, there's lots of font: "pango font description" out there,
so keep parsing this, with a deprecation warning.

dcd20e17e5 Fix parsing of the font: shorthand
Our code here was just throwing it at PangoFontDescription.
Fix this by parsing the various components ourselves.

df08fc91bd css: always get default font size in pixels
Fixes a couple bugs...

 - Pixel font sizes in css would render as point sizes.

 - For em font sizes, where the parent size was set and not default, we would
   incorrectly convert a pixel value from points to pixels.

We'll always grab the default font size in pixels so we don't keep confusing
things.

Worth noting that gtk css font-size will still behave differently than the
web. Pango interprets font-size differently.

a52ecd2be6 css: Add gtk_css_number_value_can_parse()
Use it instead of _gtk_css_parser_has_number().

We need that once we introduce calc() support.

e2d966eda5 cssnumbervalue: Remove gtk_css_number_value_get_unit()
This is in preparation for calc(), as calc(50% - 5px) is valid CSS
but has 2 units. Instead, add a function to query a value's dimension
(so we can differentiate lengths from numbers) and add a function to
query if the value contains percentages.

f61b7ba797 Prefix outline radius CSS properties
These are not in any CSS specifications, so mark them as GTK+
additions by giving them a -gtk prefix. The old names still work.

5ad60caa3c css: Implement font-stretch
The font-stretch CSS property is defined in the Level 3 CSS Fonts
module, available at:

  http://dev.w3.org/csswg/css-fonts/#propdef-font-stretch

It allows defining a normal, condensed, or expanded face to the font
description. Pango already supports it, so this is literally just the
CSS parser machinery needed to bridge our CSS to the FontDescription
API.

b3b83545c4 Don't return prematurely
This code was clearly meant to return _after_ the loop.
Don't put the return inside the loop body, then.

4e09e180e4 Fix css parser tests
Parsing a shorthand background property was running into unexpected
errors when trying position values where there were none. To fix this,
introduce a try_parse variant of the position parse function that
silently returns NULL.

7603e6e473 css: Use GtkCssValues instead of GValue in the css machinery
Also, in places where we're computing a new CssValue based on an

to the old one, rather than creating a new identical instance.
