css: Emit deprecation warnings only under debug

Not every CSS provider can drop deprecated CSS constructs, especially
if they are forced to maintain backward compatibility with third party
code, like libadwaita.

The slightly annoying part is that we cannot use GTK_DEBUG_CHECK, as we
cannot include gtkdebug.h inside gtkcssparser.c, so we need to hack our
way around it.

+## Custom Properties
+
+GTK supports custom properties as defined in the
+[CSS Custom Properties for Cascading Variables](https://www.w3.org/TR/css-variables-1)
+spec.
+
+Custom properties are defined as follows:
+
+```css
+--prop: red;
+```
+
+and used via the `var` keyword:
+
+```css
+color: var(--prop);
+```
+
+Custom properties can have a fallback for when the referred property is invalid:
+
+```css
+color: var(--prop, green);
+```
+
 ## Colors
 
+### CSS Colors
+
+Colors can be expressed in numerous ways in CSS (see the
+[Color Module](https://www.w3.org/TR/css-color-5/). GTK supports
+many (but not all) of these.
+
+You can use rgb(), rgba(), hsl() with both the legacy or the modern CSS
+syntax, and calc() can be used as well in color expressions.
+
+### Non-CSS Colors
+
 GTK extends the CSS syntax with several additional ways to specify colors.
 
+These extensions are deprecated and should be replaced by the equivalent
+standard CSS notions.
+
 The first is a reference to a color defined via a @define-color rule in CSS.
 The syntax for @define-color rules is as follows:
 
 ```
-@define-color Name Color
+@define-color name color
 ```
 
 To refer to the color defined by a @define-color rule, prefix the name with @.
 
+The standard CSS mechanisms that should be used instead of @define-color are
+custom properties, :root and var().
+
 GTK also supports color expressions, which allow colors to be transformed to
 new ones. Color expressions can be nested, providing a rich language to
 define colors. Color expressions resemble functions, taking 1 or more colors
 and in some cases a number as arguments.
 
-`lighter(Color)`
- : produces a brighter variant of Color
+`lighter(color)`
+ : produces a brighter variant of `color`.
 
-`darker(Color)`
- : produces a darker variant of Color
+`darker(color)`
+ : produces a darker variant of `color`.
 
-`shade(Color, Number)`
- : changes the lightness of Color. The number ranges from 0 for black to 2 for white.
+`shade(color, number)`
+ : changes the lightness of `color`. The `number` ranges from 0 for black to 2 for white.
 
-`alpha(Color, Number)`
- : replaces the alpha value of color with number (between 0 and 1)
+`alpha(color, number)`
+ : multiplies the alpha value of `color` by `number` (between 0 and 1).
 
-`mix(Color1, Color2, Number)`
- : interpolates between the two colors
+`mix(color1, color2, number)`
+ : interpolates between the two colors.
