Follow-up to CR by Benny:
Removed redundant forced conversion to float, the
from future import division
handles that already. See PEP-238 for details.
draw_text:
Remove manual layout wrapping, use pango Layout logic.
Refactored wrap_truncate_layout from draw_arc_text,
and it's now reused in draw_text, here with CHAR
wrapping mode as opposed to WORD in draw_arc_text.
This replaces the (Unicode-wrong) implementation of
manual char-by-char code with text truncation.

gramps/gui/utilscairo.py:
new file, currently holds just the warpPath() function,
taken from /usr/share/doc/python-cairo/examples/warpedtext.py,
with explanatory docs added.
gramps/gui/widgets/fanchart.py, class FanChartBaseWidget:
draw_text() method:
previous logic using cairo toy text API didn't support CTL text.
It has been removed, and replaced with a call to a new
method, draw_arc_text().
Flagged a subtle Unicode issue in the remaining old code,
for radial-oriented text, with a FIXME, I'll probably fix it
later as a separate issue.
create_map_rect_to_sector() static method:
create a transform to use with gui.utilscairo.warpPath(),
currently used in draw_arc_text().
Following Benny's code review I have annotated the algorithm
and made it hopefully clear, but I guess it could be reworked
into a better form if re-expressed with stacked transforms /
complex numbers / matrices for easier later maintenance.
Meanwhile I have used the same approach as the older code
in the file, good enough for a patch under this feature request.
The only issue remaining from the code review is whether
the create_map_rect_to_sector() function should be moved
to gui.utilscairo; see the bug thread.

Only one base translation per locale. To set up a different locale
on any axis (locale, domain, directory, or languages) instantiate a
secondary locale by calling GrampsLocale() with the appropriate
arguments.
svn: r21968
With GrampsLocale.sort_key (for strxfrm and conv*_tosrtkey) and
GrampsLocale.strcoll.
If ICU is available will use the correct ICU::Collator for the locale,
otherwise falls back to locale.strxfrm -- for which it temporarily
changes the LC_COLLATE locale.
