1f3327d326 rgba: Use pango_color_parse_with_alpha 
Use this newly exported pango function, so we
can support hex colors with alpha like #rrggbbaa.

2d5cf2b4c4 Drop fallback-c89.c 
We require a C compiler supporting C99 now. The main purpose of
these fallbacks was for MSVC. From what I can see this is now all supported
by MSVC 2015+ anyway.

The only other change this includes is to replace isnanf() with the
(type infering) C99 isnan() macro, because MSVC doesn't provide isnanf().

89fb752a8f css: Use %f, not %.17f

d71c196c5c css: Don't print numbers with exponent 
CSS does not do exponents, so printing numbers close to 0 as 1.234e-15
does not work.

Also up the accuracy to 17 digits because that's what everyone else
uses.

98e076b51e rgba: Add gdk_rgba_parser_parse() 
This function is a (private) function to parse a GdkRGBA accoridng to
the CSS specs. We should probably use it for gdk_rgba_parse(), but that
would change the syntax we accept there...

This also introduces a dependency of libgdk on libgtkcss.

So far, no users for this function exist.

4c150d8eb5 The big versioning cleanup 
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.

071c9a8221 API: gdk: Add gdk_rgba_is_clear() and gdk_rgba_is_opaque() 
I want to use these inside GSK, and I'm not a fan of putting GdkRGBA
APIs into it or duplicating it into GTK.

So public API it is.

a85384135c Revert "Add missing (out) annotation to gdk_rgba_parse" 
This reverts commit 695860958a.

The change introduced an introspection ABI break.

See also: https://bugzilla.gnome.org/show_bug.cgi?id=682125

If we want to move the parse() method to be a constructor or a class
method, we'll need to do more testing or add new API.

1779ae79a1 rgba: Invert the arguments and improve bindability 
Since parse() is a method of the Gdk.RGBA class, the GdkRGBA pointer
should be the first argument, and the string the second one, to allow a
more natural binding.

5daab52661 Switch to CSS interpretation of rgb() and rgba() colors 
CSS3 defines a somewhat odd syntax for rgba() colors - the rgb values
are integers from 0 to 255 or percentages and the a value is a
float from 0 to 1. To avoid increasing the total amount of confusion
in the world, make gdk_rgb_to_string() and gdk_rgb_parse() follow
this syntax rather than using floats for r, g, and b.

5a5f8081f0 Add GdkRGBA struct to supersede GdkColor 
GdkRGBA is a boxed struct similar to GdkColor, with the difference
that it stores alpha information as well, and colors are stored in
[0..1] doubles, in the cairo spirit.

gdk_cairo_set_source_rgba() has been also added to allow easier handling
of this new type.
