_cairo_clip_get_surface() expects the caller to handle unaligned clip
boxes in order to avoid recursion. The baseline renderer ignored this
basic tenet and so ended up with only sharp clip regions.

Uli Schlachter spotted that I had create reference images with sharp
edges for his tighten-bounds test case, exactly as if I had ignored
unaligned clip boxes...
Turns out I had removed the code to handle them...
I'm not quite sure how we end up with a pair of colinear edges both with
a deferred trap...

The test-traps provides a reference implementation of the
traps-compositor as used by xlib, so we can use it to generate the
reference images as well. (Of course checking that test-traps is itself
correct and only differs in the renderer! ;-)

With over two thousand references images now, it is starting to make the
test directory look cluttered!

Most fonts use Window platform specific encoded font names since they
allow unicode names.
- Make _cairo_truetype_read_font_name() read the Windows platform
names first. If this fails, fallback to reading he the Mac platform
MacRoman encoded name.
- Use the PDF method of encoding non ASCII PS font names. Poppler will
correctly extract the unicode name.
- Make PDF embed the font family name as AsciiHex if the name is not ASCII.
test-base basically implements rendering ala cairo-1.0 and so serves as
a useful baseline for comparing enhancements and to regression test the
core libraries.

surface->use_pixmap always had the value 0. This code is taken from cairo-xlib.
However, in cairo-xlib use_pixmap is set to 20 if XGetImage() fails.

Fixes the cairo-xlib crash with tighten-bounds. (I thought I had fixed
it earlier, but I was obviously wrong.)

According to the little fishies this performs significantly better.
As a bonus, it did not handle overlapping boxes correctly...
