This one uses the ActiveMesh::VolID.
But old version works actually better due to spatial-overshoot...

Rendering of texture was spit into three phases.

Added one new param to ActiveMesh::ImportVTK_Volumetric()

Gaussian-smoothing-based FF creation finished -- ActiveMesh::ConstructFF()

RenderMesh() updates fl. dots position based on the intermediate FF.

Updating does not handle growing filopodia!

Added ActiveMesh::ConstructFF() and ActiveMesh::RotateVolPos().
Finished ActiveMesh::FFDots().
Added GetPixel().

RenderMesh() in main.cpp features coherent texture rendering (but without following mesh deformation...)

Added macro: SAVE_INTERMEDIATE_IMAGES

ISOTROPIC version, first one. Resampled for anisotropic closer to the end.

wtf?

Batch is producing masks and texture (modified RenderMesh()).

Normals are not used when drawing triangle edges.

VTK reading must change the order of triangle vertices when importing them

Finished tweaking of OpenGL vizual mode (depth buffer on, backfaces culling)
