The libsvg TODO 
---------------
(sorted roughly by intention)

Non-critical, relatively minor
------------------------------
Add svg image support.

Fix to not preserve whitespace by default.

Resolve proper rendering of width 1 lines (see "Fail, due to secondary considerations" below)

Fix units (come up with a general solution for dealing with 100% on outer <svg>)

Fix aligning of text, (note that text-alignment-BE-10 breaks when scaling)

Big work ahead
--------------
Add gradients

Add clipping/masking

Add filters

Add whatever else is missing to bring all other tests into conformance

Conformance Testing Status
==========================
Here is the status of libsvg with respect to the tests from the W3C
conformance suite. The test suite is available from:

	    http://www.w3.org/Graphics/SVG/Test/

The status below reflects results from the xsvg viewer using libxrsvg
which uses Xr and libsvg. Hence, some of the failures noted below
could be bugs in xsvg, libxrsvg, or Xr rather than directly in libsvg.

Test are grouped according to their behavior:

Pass perfectly [*]

[*] There is one big difference between my images and the reference images:

    The SVG conformance suite reference images have width 1 stroked
    rectangles, (with integer coordinates), occupying one row of
    pixels. This is in contrast to my current output which occupies 2
    rows of pixels (each at 50%). My current result is more "correct"
    geometrically, but it looks nasty. I found language in the
    spec. saying that all results had to be within 1 pixel of the
    geometrically correct result. Also, property controlling this has
    a default value of "auto" which means the user agent is allowed to
    tradeoff geometrical accuracy for crisp edges.

    So, I think the results I have conform, but I want to find a clean
    way to get these silly width 1 rectangles nice and crisp and
    matching the reference images.

Fail, but look hopeful
