[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.

[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.

[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.

[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.

[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.

[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.

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
