- 'extern "C"' fix for MSVC as suggested by Stephane

While looking at the python Lattice code for a bug, I instead found
what must clearly be a typo ... an 's_z' where an 's_y' should be
-- python Lattice module owner please check!

Bugfix (own discovery!), using sequencer to render a scene updated the
depsgraph 2 times to often, also confusing particle drawing when disp %
is set.

And: little cleanup in render code (move includes in order)

MSVC6 projects
adding libtiff files to compile

Bugfix #3437 #3438

- Mirror modifier showed particles on wrong half.
Note: particles don't do modifiers yet (apart from using subsurf coords)
- Boolean modifier copy didn't copy the 'operation' type.

I hoped we could skip a floor() in the new zbuffer code, but no...
rounding negative values goes to zero, caused left pixel to not
render in images.

Forgot to remove code that draws the jitter samples in camera view!

Forgot to note in previous commit: also cleaned up warnings in code,
like using exported functions without adding it in the .h.

New stuff & fixes in Blender OSA filtering.

While investigating alternative filters (Mitchell), I found two small
errors in the Gauss code, it clipped wrong and multiplied wrong, causing
settings other than filter size 1.0 to not work properly.

Took the last-minute liberty to add more filter types in Blender too.
Also wrote an extensive log about how sampling & filtering in Blender
works.

- temporary fix for MSVC (accessing a var from the elbeem lib
caused trouble)

Adding libtiff for win32 build

added bad level call stub for sluidsim

With the holy blessing of guitarGeek: Using smooth on a mesh with a
mirror modifier and the clipping option now preserves verts on the
plane(s) of symmetry (i.e., those verts are smoothed, then projected
back to the plane(s) of symmetry).

uh should have read the patch better, i did test it and it works :)

adding libtiff info to scons, applying http://vidar.gimp.org/tmp/scons-linux.diff

* Attempting to fix scons for mac os x. It seems to be correct, if I've made a
mistake, someone can please help fix, just trying to get things to compile here
in the studio. You'll need to delete config.opts

- solver now supports animated time steps, gravity
and viscosity, an example can be found here:
http://www10.informatik.uni-erlangen.de/~sinithue/temp/fluid_timeanim.mpg
- for simulation time animation the time IPO of the object is currently used,
for all three there should probably be new ipos in the fluidsim struct
- started the API in elbeem.cpp, to get rid of parser & export
via HD (it's not yet used)

- changed DerivedMesh integration, the fluidsim meshes now
replace the original one. so modifiers now work with them
(apply modifier, or edit mode still work on original mesh).
this should fix the three fluidsim bugs in the tracker.
- fixed stupid makesdna problem (writing "char string[160+80]" isnt
a good idea :)
- changed GUI a bit, now displays an estimate of the required memory,
there's still a problem with redrawing (currently relies on a call
to the derived mesh generation)
- the fluidsim struct changed to store the bounding box,
and the current loaded surface mesh
- temporary simulation files are now removed if env. var.
BLENDER_DELETEELBEEMFILES is not set or zero
- fluidsimSettingsFree now gets properly called when freeing an object

- added dynlibtiff.c and tiff.c for compilation
