f6c15198bc [apps/regression] Power regression uses logarithm of series 
This matches other apps results and we directly compute the values from
the data instead of doing a gradient descent.

a8ead6b66e [apps/regression] Better initialisation of logistic model coefficients 
It provides a better fit for:
x = {0.0, 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0}
y = {5.0, 9.0, 40.0, 64.0, 144.0, 200.0, 269.0, 278.0, 290.0, 295.0}
(coeffs should be {64.9, 1.0, 297.4})

2dee8f2b1f [apps/regression] Fix cursor redrawing when changing cursor type 
Scenario:
double x[numberOfPoints] = {0.0, 0.975, 1.97, 2.945, 3.971, 4.887, 5.924, 6.964, 7.979, 8.974, 9.998};
double y[numberOfPoints] = {-23.784, -23.322, -28.322, -18.422, -4.813206, 7.146241, 16.631, 16.632, 9.209189, -6.050863, -19.659};
Quadratic regression, navigate on the points then go on the
regressioncurve -> there is a drawing glitch
