These are always set to the same value as the corresponding border
radius properties. They are also non-standard, so remove them and
replace them with the border radius properties everywhere.
Fixes#2414
We want to differentiate what requires recreating the
texture and what doesn't. In particular, the current
flags are not handling symbolic icons right.
Previously, we wrapped all GtkCssShadowValues in a GtkCssShadowsValue,
even if it was just one shadow. This causes an unnecessary bloat in
css values.
Make each GtkCssShadowValue able to handle multiple shadows instead, and
use gtk_css_shadow_value* API everywhere.
The differenciation between a literal color value and an RGBA value
caused problems in various situations. Just treat the two the same but
don't allow access to the rgba value of a non-literal color value.
This gets rid of around 1.6k rgba values in the widget-factory.
This avoids invalidating the size of all widgets when updating CSS
transforms.
In theory, we don't even have to allocate the widget itself, because we
didn't change its size. But we have no way to track that.
Now that queue_draw() isn't restricted to clip anymore, we don't need to
care about clip in the CSS engine either.
We do keep GTK_CSS_AFFECTS_CLIP around though because GtkWindow does
care for the window's size.
Nobody's doing that. And CSS Images are no longer using Cairo anyway.
If we wanted to support querying them (hint: we don't) we should be
using GdkPaintable.
It was used to mark css properties that affect widgets with text, but it
caused unnecessary invalidations. E.g. 'color' was marked as
AFFECTS_TEXT but changing just the color of a label should not
automatically queue a resize, which is what the code in
gtk_widget_real_style_updated does.
Replace this flag with GTK_CSS_AFFECTS_TEXT_SIZE and
GTK_CSS_AFFECTS_TEXT_CLIP, which GtkWidget can use only if the widget
actually has text.
As Benjamin says, ident should only be used if any value
is valid, which is not the case here. So use enums instead,
which should also be more efficient. To handle the more
complicated cases like font-variant-ligatures, we have to
introduce flags-like values.
Drop the current css2-style font-variant property and
replace it with a shorthand as specified in the css3 fonts
module. Currently, we fully support the font-variant-ligatures,
font-variant-position, font-variant-caps, font-variant-numeric
and font-variant-east-asian subproperties. font-variant-alternatives
is only partially supported.
The outline-{top,bottom}-{left,right}-radius names have been
deprecated for a while, so lets remove them. Everybody should
just use the -gtk-prefixed names for these properties.
Previously, for compatibility with GTK 3.0, we allowed specifying
numbers without units and interpreted them as pixels, even when the CSS
specification didn't.
Remove that now that we can break API.
