ROADMAP
=======

Also see gtk-css-engine's TODO for now.

0.2
---

* Finish per-node CSS ("style=''").
* Merge universal- and type-selector based blocks in a single step, fetching the respectively next every time. Maybe use a hash and iterators internally, instead of GTree?
* Pass pseudo class(es) to the drawing function(s) instead of determining them at query time.
* Move `none' and `inherit' out of the structs and into an own hash (save mem).
* Consider a custom allocator (gslice?) for same-sized properties (find out how much overhead regular malloc has for small structs first).
* Implement public selector-group API in terms of stylesheet?
* ccss_stylesheet_new_from_file took (filename, GError)
* Better function interface, so it can also be used for gtkrc settings:
    GtkButton {
      gtk: xthickness(3);	/* Or just "xthickness: 3;" for this special case? */
      GtkButton: child-displacement-x(0);
      GtkButton: default_border( 0, 0, 0, 0 );
    }
* Query interface through CSS selectors, see gtk-css-engine TODO.
* Callback-based stylesheet-iteration API, then selector-group can be totally internal. Get rid of <glib.h> in all public headers.
* There is currently no way to free inline blocks, e.g. when a document is dynamically creating and deleting nodes with inline styling. In this case the inline styles will live as long as the stylesheet they are associated to.

0.3
---

* Separate cairo-dependent code.
* Create a "grammar" class that holds properties and functions, needs to be passed when allocating a stylesheet.
