UMVE: Fixed tone mapping histogram for zero float values
UMVE: Fixed deleting mesh faces, will now also delete face normals
DMRECON: discard dz and conf maps by default

We don't need those often, so don't clutter the views.
DMRECON: add options --keep-dz and --keep-conf

libdmrecon doesn't write those by default, so add an option.
UMVE: add options to keep dz and conf maps

libdmrecon doesn't write those by default, so add an option.

UMVE: added options to keep dz and confidence maps
DMRECON: use T::Ptr, not RefPtr<T> or TPtr
Merge pull request #34 from Waldteufel/style

DMRECON: use T::Ptr, not RefPtr<T> or TPtr
MVE: Fixed string conversion in case of the empty string
Merge branch 'master' of github.com:simonfuhrmann/mve
DMRECON: specify defaults in mvs::Settings only
UMVE: use default values from mvs::Settings

Always read default values from mvs::Settings so that they are the same
in dmrecon and UMVE.
DMRECON: make use of scaled matrices explicit

Previously, calling some of SingleView's methods on a reference view
meant using matrices matching the reconstruction scale.

Make this explicit.
DMRECON: group projs and invprojs in img_pyramid

Also keep the original color image in img_pyramid[0]. Together this
saves some checks for level == 0 and should improve readability.
DMRECON: create image pyramid immediately

Create the image pyramid immediately after loading the color image.
This will be needed for an optimization.
DMRECON: allow only integer scales

Fractional scales are rarely used, so only allow integer scales.
This will be used in an optimization.
UMVE: don't cast dmrecon scale to float

As dmrecon now only allows integer values, this cast is unnecessary.
DMRECON: pick scaled_image from image pyramid

Scaling the image with rescale_gaussian is slow, pick it from the
image pyramid instead.

This change causes small differences in the resulting depth maps.
