The linear things should be drawn in drawFunction() since they
change only when some control point is moved and the spline is
recalculated anyway.
Introduce spline::get_value_no_save to avoid clobbering the
tracked value.
Draw linear helper before the spline to avoid occluding it.
Remove some redundant checks for whether _config exists when all
calling sites ensure it already.
I still need to de-camel-case these two classes.

Unfortunately now spline widgets grab keyboard focus. Qt doesn't seem to have a
better way to detect whether some other application gained focus.

Tooltip shows current cursor/point position.
Factor out common functions. Use QPoint/QPointF appropriately.
Remove rounding that led to snapping to integral values. Allow for non-integral
snapping amounts.

In case mem<settings> is still used elsewhere we still have a use-after-free
otherwise.

- add missing locking
- bundle and settings ptr are never null following initialization;
sentinel objects get created if there's no bundle, thus don't branch
outside initialization functions. the sentinel object doesn't load or
save to the .ini file
- connect spline refresh to any bundle change
- connect spline widget refresh to spline refresh
- few caveat comments
- spline_widget::setConfig now only takes the spline as argument,
eliminating most of the complex logic there
- clarify spline::set_bundle vs newly introduced spline::recompute

- spline widgets reload when spline bundle reloads
- every bundle reloads when profile gets changed
Importing old spline settings hasn't been implemented.
Control point positions are stored as raw floats. This is bad.
