Use negative Y if there is only 1 positive Y
Skip some 0 or 1 in some corner case.
Add minus sign if intercept is missing
Simplify writing of equation

Bloody workaround hack for the fact that Chart does not handle
category/x-axis times internally and is not able to pass its own axis
numberformat to its own databrowser editor.

They are mapped to the same entry as the exisiting ones but make it much

Fixes potential regression curve class.
For potential regression curve algorithm, we try to get y = C * D^x
Switching to neperian logs:
ln(y) = ln(C) + x ln(D)
So we make a linear regression and get
slope = ln(D) => D = exp(slope)
intercept = ln(C) => C = exp(intercept)
The current code computes the linear regression between log(y) and
log(x)
It should be between ln(y) and x.
Moreover, the slope is ln(D) so exp(slope) should be returned.
Finally, in getCurveValue, the return value is y = C x^D which is wrong

This may reduce some degree of dependency on boost.
Done by running a script like:
git grep -l '#include *.boost/scoped_array.hpp.' \
| xargs sed -i -e 's@#include *.boost/scoped_array.hpp.@#include <memory>@'
git grep -l '\(boost::\)\?scoped_array<\([^<>]*\)>' \
| xargs sed -i -e 's/\(boost::\)\?scoped_array<\([^<>]*\)>/std::unique_ptr<\2[]>/'
... and then killing duplicate or unnecessary includes,

Turn the Link class into a template abstracting over the link's argument and
return types, but provide default template arguments that keep the generic,
unsafe "void* in, sal_IntPtr out" behvior. That way, individual uses of the
Link class can be updated over time.
All the related macros are duplicated with ..._TYPED counterparts, that
additionally take the RetType (except for LINK_TYPED, which manages to infer the
relevant types from the supplied Member).
(It would have been attractive to change the "untyped" LinkStubs from taking a
void* to a properly typed ArgType parameter, too, but that would cause
-fsanitize=function to flag uses of "untyped" Link::Call.)
