Make it possible to track specified clip

Added a property to track_marker operator to be
able to render clip which name was passed to the
operator instead of clip from current clip editor
context.

Very much useful for automatic tests.

Eagerly attempt to refine a track before doing a brute search

Before the refinement phase of tracking, a brute force SAD search
is run across the search area. This works well but is slow;
especially if the guess for the track's location is accurate.

This patch runs a refinement phase before running a brute force
search, hoping that the guessed position (in x2, y2) is close to
the best answer. If it is, then no brute search is done. If it is
not, then a normal brute force search followed by refinement is
done.

In some cases this may produce worse tracks than before; the
regressions will need investigation. The predictive motion model
(to be implemented) will reduce the probability of that happening.

Triangulate Modifier: using different ngon and quad methods

Quads: Beauty, Fixed, Fixed Alternate, Shortest Diagonal
Ngons: Beauty, Scanfill

* Shortest Diagonal is the default method in the modifier (popular
  elsewhere), but beauty is the default in Ctrl+T).

* Remove the need for output slot and beauty operator to be called
after Clt+T
