We do want the -Wfloat-conversion warnings where they point out
potential bugs. But they are very distracting when they are triggered by
floating point literals (which the standard defines as double) passed to
a function expecting float arguments.

Most colors were already collected there, but a few were dispersed
throughout the source files.
For future themeability, move the remaining colors to this common
place.

This is not perfect - the polygon of the confidence area is
calculated even if it is not shown. Oh well.

Render the confidence area and the regression line into a pixmap
and show that using a QSGNode.
It is unclear whether it is preferred to do it this way or to
triangulate the confidence area into triangles to be drawn by
the shader.
