931556005a [trace] Remove the forced switching to C locale 
This interferes with the application being traced. It is not clear from
printf(3) whether "%.f" is locale dependent or not - but until we have a
failure do not break applications unnecessarily!

d0f41b92bf [trace] Do not force the output filename. 
Handle the case of tracing an application that spawns it own graphical
children but using the autonaming facility within cairo-trace. Currently
the traced process tree would all attempt to write to the same file,
creating a broken trace. This means sacrificing the display of the output
name, but allows use for a wider range of applications.

19e8c5c7f4 [test] Fix mismatched free. 
A couple of strings allocated using glib functions but freed with system
malloc.

28a72648ba [gstate] Change the glyph dropping safety margin from 2em to 10em 
The small margin caused bugs with math fonts.  See:

fa63c43532 [spline] Be pedantic and propagate errors. 
We know that the current users will always return SUCCESS, but propagate
the status return for future users.

0100856226 [path] Remove tolerance from path bounders 
With Behdad's analytical analysis of the spline bbox, tolerance is now
redundant for the path extents and the approximate bounds, so remove it
from the functions parameters.

Also make it more strict.  The only times we call sqrt now is
when a solution in (0,1) exists.

ef0f6c3ca3 [spline] Add an analytical bounder for splines 
The way this works is very simple:  Once for X, and once for Y, it
takes the derivative of the bezier equation, equals it to zero and
solves to find the extreme points, and if the extreme points are
interesting, adds them to the bounder.

Not the fastest algorithm out there, but my estimate is that if
_de_casteljau() ends up breaking a stroke in at least 10 pieces,
then the new bounder is faster.  Would be good to see some real
perf data.

50bc2bc017 [path] Simply track the current point for bounds. 
The idea is to track always update the current point, but not add it
during a move-to.

078ebb01ba [path] Initialise spline from current point 
Joonas spotted that the breakage with the curve bounds was the result of
initialising the spline using the original move to point and not the
current point.
