65f9760d66 [toy-font-face] Return defaults for error objects. 
Similar to the behaviour of the other objects, we return the default
conditions if the object is in any error (and not just a nil object).

d478d5ed5c [doc] Give a small hint about Twin font 
Though, the details are not documented yet.  I'm not sure how much of it
I do want to document.

a023104400 [trace] Adopt _cairo_dtostr 
In order to have locale-independent output of decimal values, we need to
manually transform such numbers into strings. As this is a solved problem
for cairo, we adopt _cairo_output_stream_printf() and in particular the
_cairo_dtostr() routine for our own printf processing.

c601f30843 [cairo] Early return if we attempt to set the same colour. 
Profiling a silly video renderer that called set-source; rectangle; fill;
for each pixel, we can shave 5% off the cairo overhead by introducing an
early return if we attempt to reset the current colour.

fb3522f33a [os2] Fix memory leak of surface on error path 
Of we fail to create the mutex, free the surface before returning the
failure.

8d23c3a6c2 [quartz] Delay allocation of string until after guard. 
Fixes a memory leak should we bail due to the version of Quartz being
insufficient.

9c9ed8f0b5 [scaled-font] Post-process hash value.

555dd6b97e [scaled-font] Switch to a constant loop for hashing. 
As we only use the FNV hash for hashing matrices, expose the constant size
to the compiler so that it can perform its magic.

f5274f5847 Iterate over hash table using foreach() in destructors. 
Don't use the remarkably inefficient _cairo_hash_table_random_entry() to
remove all entries from the hash table!

1c4ea84b24 [cairo] Early return if we attempt to set the same scaled_font 
If the application calls cairo_set_scaled_font() with the current
scaled font, we can return early as it is a no-op.

replacement in the escaped string!

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.

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

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.

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.
