cssimage: Fix cross-fade
...
Simgle image cross-fade opacity was computed the wrong way, which caused
weird fade-in/out animations, for example in flat buttons.
I messed this up when porting cross-fades to snapshot().

We need to actually compute the images. Otherwise,
bad things happen when we try to draw.

cssimagecrossfade: Fix order of images when parsing/printing
...
The syntax is cross-fade(<percentage> <end>, <start>), not the
other way around. That's because the percentage refers to the end image.

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.

cssimage: Implement (most of) current cross-fade syntax
...
The CSS4 spec adapted their cross-fade syntax again. Yay!
(The previous parser was completely broken anyway...)

cssimage: Make cross-fades cross-fade properly

We need to use OPERATOR_SOURCE to properly fade out the start image
when the end image contains transparency.

cssimage: Add GtkCssImageCrossFade
...
Supports the cross-fade() css notation the way the old CSS3 specs did.
The main reason for adding it is supporting image transitions though.
