As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

For -O2 gcc activates -fstrict-aliasing. As a result the compiler is
allowed to assume that pt[1]=px[1]/3+B1 does not affect t.
Therefore the result of _fast_cbrt() was always 0.
Using a union for casting avoids this issue.
For more details see:
http://labs.qt.nokia.com/2011/06/10/type-punning-and-strict-aliasing
Also the updated code respect endianness.

I added the possibilty to define Bezier/TCB splines and use them
as custom easing curves.
Note:
Splines have a parametric definition. This means we have a
function/polynom of t that evalutes to x and y. x/y = f(t).
For our purpose we actually need the function y = f(x).
So as a first step we have to solve the solution x = f(t) for a given
t and then in a second step we evaluate y = f(t).
f(t) is a cubic polynom so we use cardanos formula to solve this equation
directly.
For the casus irreducibilis we need 3 functions that are a combination of
arcos and cos. Instead of evaluating arcos and cos we approximate these
functions directly.
TCB splines are converted into the corresponding cubic bezier spline.

This is the beginning of revision history for this module. If you
want to look at revision history older than this, please refer to the
Qt Git wiki for how to use Git history grafting. At the time of
writing, this wiki is located here:

If you have already performed the grafting and you don't see any
history beyond this commit, try running "git log" with the "--follow"
argument.
