Cleanup: Move all Shader creation to engine_init

updated adaptive time stepping

moved adaptive stepping loop out of manta simulation (python) and into big step (update flows + update obstacles + manta simulation) (blender c)

Merge branch 'master' into soc-2017-normal-tools

Merge branch 'blender2.8' into greasepencil-object

Merge branch 'master' of git.blender.org:blender into collada

Fix Collada: Export of sampled animations exports nothing

When exporting animations as matrix data, the exporter did not
create anything. This was because i forgot to copy the sampled
object matrix to the BCSample while decomposing the matrix.
The fix makes sampled animation export work again

Refactor Collada: Renamed files to better match class names:

* Renamed files:
old names: BCAnimationCurveContainer.*
new names: BCAnimationSampler.*

* Adjusted the include files to the new names

Refactor Collada: simplified API

replaced methods from BCAnimationCurveContainer:

BCSample &add(Object *ob, Matrix &mat);
BCSample &add(Object *ob, Bone *bone, Matrix &mat);
BCSample &add(Object *ob, Matrix &mat, int frame_index);
BCSample &add(Object *ob, Bone *bone, Matrix &mat, int frame_index);

by much simpler methods:

BCSample &add(Object *ob);
BCSample &add(Object *ob, int frame_index);

Refactor Collada: BCMatrix is now decomposed on init

Previously the BCMatrix object was decomposed when needed the first time.
But since the decomposition is done always for every single Matrix,
we can do it right upon construction with the additional benefit that
we can handle euler rotations nicer, see

void BCMatrix::set_transform(Object *ob)

There we now can use quat_to_compatible_eul() to avoid axis flipping
during exporting of object transforms. (todo: apply this also for
bone animations)

Fix Collada: added missing private: to CBSample declaration

Refactor: Added useful typedefs to BCSample.h

Fix blur shift when add more samples

The image was moved to top when increase the sample number. This was due the shader was bluring both axis at the same time.

Cleanup: Use always even numbers for samples

Cleanup: Simplify shader parameters

Cleanup Collada: Change variable name from sample to matrix

this was a leftover from a previous cleanup where i separated
the old BCSample into 2 classes BCSample and BCMatrix

Restructure VFX Blur, add Samples and cleanup

Now, the number of defined passes is low and there is a new parameter to define number of samples.

Merge branch 'blender2.8' into greasepencil-object

Cleanup unused variable

Replace constant bokeh value by parameter

Fix compilation error after merge
