improvements
============

Selector
--------
:prio: 1

- CSS2XPath converter -> use lxml.cssselector
- optimize selector parsing?
- **add query functionality**
    + specificity DONE
    + cascade


test improvements
-----------------
:prio: 1

- Token.EOF handle in all classes for end of stylesheet

    User agents must close all open constructs (for example: blocks, parentheses, brackets, rules, strings, and comments) at the end of the style sheet.

- line/col reporting tests
- tests with almost all details with comments
- check escape handling::

    \\@a \\{ \\: : \\; ; \\} }
    .\1 is valid selector

- csshack tests, see online tables (comment hack?)
- test tigris.css
- implement testsuite on HTML? http://www.w3.org/Style/CSS/Test/CSS3/Selectors/current/xhtml/index.html

- CSSStyleSheet.setSerializer()
- CSSStyleSheet.setSerializerPref()


CSS2Properties
--------------
:prio: 2

needs to be implemented fully, setting of margin: 1px sets actually marginTop, marginLeft etc


CSSValue
--------
:prio: 3

**this feature may be implemented later as CSSOM defines the complete thing differently**

implement RGBColor, Rect and Counter

serializer
~~~~~~~~~~
- add preference option how color values should be serializer:

  ser.prefs.COLORS_HEX, also the DEFAULT?
        e.g. #123, so short form is possible
        ignored for rgba()
  ser.prefs.COLORS_HEXFULL
        e.g. #112233, so always 6digit hex
        ignored for rgba()
  ser.prefs.COLORS_RGB_INTEGER
        e.g. rgb(1.1, 55, 255), so range from 0-255
        also for rgba()
  ser.prefs.COLORS_RGB_PERCENTAGE
        e.g. rgb(10%, 20%, 100%), so range from 0 to 100%
        also for rgba()
  ser.prefs.COLORS_FROM_SOURCE
        use colors as used in CSS Source

  additionally:
    ser.prefs.NAMED_COLORS
        e.g. white for #fff or rgb(100%, 100%, 100%)

- **refactor**: all preferences values should be constansts like above

performance
-----------
:prio: 3

- profile.py
