Merge branch 'ISBI2016_TextureRenderer' of https://gitlab.fi.muni.cz/xulman/ISBI2016-filaSimu-TM into ISBI2016_TextureRenderer

and various types of noise in the last simulation stage.
Additionally, the histogram is fine now. It is nearly the same as the
histogram of real images.

Tips are addressed as filoID+branchID (latter unique within only within its filopodium).

Ale the importer considers the skeleton segments ID as a guide for reliable filopodia tip tracking.

(which is a consequence of the new plan between GM and TM
that filopodia VTKs may not use sequential numbers in their
filenames... hence, if 04 fails to load, we cannot assume that
there is no 05..).

to determine size of the output images.

Generator, BUG: When Phases II and III are not required, texture image shouldn't be exported (its the same as phantom anyway).

hence the previewing of meshes does not suddenly end like it used be before.

It can load and display full meshes at next, previous time points.

Scaling and translations removed.
Since mesh is not changed, it's re-reading for export is dropped.

even when it reads STL (not just after VTK import),
the same translation is used when loading mesh after GUI request.

(it was skipping the right section reading the next one instead, which of the same name unfortunately).

(not a fixed scaling and translation anymore).

- distribution of fluorescent points along filopodia
- modification innner structure of nuclei
- modification of camera noise to resemble the real images

BUG fixed: The pressurator was creating the hint image (and txt files reports) according to the size of the power noise image, ignoring the demanded number of frames.

It reports original vertex coordinates, i.e., those that one can find directly in the VTKs,
i.e., without any scaling nor translating them.
