7d768d2159 In calcOpticalFlowSF, fixed several uninitialized uses of matrices.
This should fix that pesky test failure that pops up from time to time.

I don't actually know if the default values should be zeros, but the tests
pass, so...

d9f71b762f Deleted almost all of the precomp.cpp files.
Looks like we don't actually use them; when creating precompiled headers
with Visual C++, a dummy .cpp is created at build time.

29b13ec1de Replaced most of the usages of parallel_for with that of parallel_for_.
This should allow many algorithms to take advantage of more parallelization
technologies.

6062601c4d Make rescaling flexible and add median filtering
Previously the pyramid was done with a rescaling factor of 2 (implied by the
use of pyrDown). This often leads to inferior results compared to a scale step
of e.g. 0.8 (a factor of 2 is obviously faster). This commit makes the scale
step configurable and uses a resonable default value.

The other change in this commit is that median filtering is added. This is not
described in this paper but it is done in the author's implementation. (See
e.g. "Secrets of optical flow estimation and their principles", Sun et al.,
CVPR 2010) This serves as periodic outlier removal during optimization, leading
to smoother flow fields while preserving motion edges. This includes splitting
the optimization loop into two loops.
