62b2f979e5 csstokenizer: Collect error, don't just emit it 
This again is part of the quest to make it possible to "undo" reading
a token.

c6951488f9 csstokenizer: Refactor to add GtkCssTokenReader 
This new internal struct is now used to read the next token. This allows
keeping the current info in the tokenizer.

Technically, we could now reset a parse if we wanted to. So far we don't
want to.

935141b915 csstokenizer: Export GtkCssLocation 
And change the tokenizer API to return the location instead of having
multiple functions returning all of the members of the location struct.

And because surprisingly the new Location struct is exactly the same
struct as what is used in the CssEditor (how could that happen?!), use
it there, too.

87eeb1bdfb cssimage: Add token parser for linear-gradient 
This requires refactoring of gtk_css_token_source_consume_function() to
allow a single call to the parse_args function to consume multiple
arguments.
Because the first argument to linear-gradient() is the optional
direction, we need to indicate that we skipped it. So the parse
function returns 2 in that case. This way we can set the minimum required
arguments to 3, while still allowing
  linear-gradient(red, blue);
which is equivalent to
  linear-gradient(to bottom, red, blue);

28babd269b css: Move fallback parser to GtkCssImage 
Now that all CSS values can be parsed by the token parser, no fallback
parsing code is necessary anymore.
However, the images can't be parsed by the token parser yet, so the
fallback code moved there.

Also remove the property argiument from the token parsing vfunc in
GtkCssStyleProperty. It was unused and just caused a lot of casting.

945bddf120 css: Add gtk_css_token_source_consume_number() 
This is totally so we can parse
  color: rgb(calc(255 * 0.3), calc(255 * 0.6), calc(255 * 0.3));
which Webkit totally can, but Firefox and IE totally can't.

And GTK has to be at least the 2nd best CSS engine in the world.

included.
