... 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.
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.
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.
... and take an optional style property as argument. This way, we can
allow custom parse functions for properties. The style property needs to
be optional so that we can use it for widget style properties, too.
Name it _gtk_style_property_print_value() and actually pass it the style
property. This way, we can later change it to use custom print functions
for different style properties.
The call to gtk_border_free() within unpack_border() felt completely
in the wrong place, as the border actually pertains to the GValue
being unpacked. Plus, the GValue itself was also being leaked.
In finalize(), clear all rulesets.
In parse_declaration(), Free the GValue under unhandled error situations.
In gtk_css_provider_load_internal(), Do not leak the file contents.
GValues stored in GtkCssRulesets are gslice managed, so don't
g_memdup() GValues from shorthand properties. This fixes
memory corruptions when reloading contents in a GtkCssProvider.
Shorthand properties are basically the same a in CSS. For storage in
style properties or the CSS provider, they are unpacked into the real
values, so it is possible to partially override them.
No properties are yet converted to the new world yet, this is just the
code for supporting them.
This provides a huge speedup as we only need to preprocess style
properties when they are indeed inherited. This roughly doubles the
performance of the CSS matcher and brings the time taken by
gtk_css_provider_get_style() from 19% to 7% in my favorite benchmark.
One for the style properties, one for the widget style properties.
This way we can make one hash table by pspec which means we don't have
to repeat the pspec lookup.
Keep rulesets as an on-stack/heap structure instead of allocating all
instances separately.
Also, pass a ruleset to the ruleset parser, so we can make the ruleset
parser do lots of fancy things that might be useful for performance.
Previously we got the list of all matching rules and then iterated it to
find the first one that had the property. Now we look while matching
rules, so we don't lookup rules that we don't need.
