[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.

[path] Simply track the current point for bounds.

The idea is to track always update the current point, but not add it

[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.

Fix _compute_transform to check for nearly degenerate matrices
...
If a matrix was something like [0 .000001 0, .000001 0 0] the old code would
assume that xx and yy were greater than 0 and turn the nearly degenerate matrix
into an actual degenerate one. This caused things to blow up later on. Now we
check that our nearly rectangular matrices are not nearly degenerate, and let
the nearly degenerate ones fall through to the non-rectangular path.
Note: I'm not sure why NEARLY_ZERO(d) is fabs(d) < 1/65536 instead of some
other value. Hopefully, it's a useful definition.
This problem was found by a test case attached to:
