This patch series moves the piecewise linear function class from
the Rasberry Pi IPA to libipa so that all IPAs can use it.

First an addition to the geometry header is needed, to add a
floating-point version of the Point class, then the pwl is copied over,
and the Raspberry Pi IPA is converted to use the libipa Pwl class.

The main changes in v2 are s/FPoint/PointF/g and improving the
documentation.

v3 has almost no change...

v4 adds/fixes documentation.

v5 mainly replaces the public API PointF with an libipa-internal Vector
class, which is then typedefed to PointF to be used in Pwl.
Documentation is also improved/fixed.

v6 fixes the order of adding pwl to meson.

v7 mainly fixes documentation and license in the Vector class.
