While the specific overflow issue may be fixed, loading the repro .blend
files may still crash because they are incomplete and corrupt. The way
they crash may be impossible to exploit, but this is difficult to prove.
Differential Revision: https://developer.blender.org/D3002
Sanitize a bit how cache path is handled by fluidsim (there is much more
to be done here though :( ), and forbid empty path (we reset to default
path relative to current .blend file in case it's empty).
If people really, really want to use current OS-wise directory, they can at
least use '.' as path. ;)
The redundant terms were harmless but check an expression we already
know to be true (from earlier in the same conditional).

of threads to the number of cores when the fluid is created. Rather it is now
set to 0 which means "use the number of threads specified for the scene".
Also fix:
- Fluid simulation was always lagging 1 frame behind: E.g. the 250th frame in blender showed 249th frame of the fluid simulation.
Change:
- Animated enabled/disabled property only gets counted as "on" if value >= 1
Note that this bugfix should solve many problems with timings of animated fluid sim properties.
* Replaced the hard coded viscosity presets with Python ones.
* Added version check, so older files load fine.
Loading new files into 2.62 also works fine.
Not all file formats/calls are supported yet. It will be expended.
Please from now on use BLI_fopen, BLI_* for file manipulations.
For non-windows systems BLI_fopen just calls fopen.
For Windows, the utf-8 string is translated to utf-16 string in order to call UTF version of the function.
This was a request by Daniel Salazar. It adds a new frame offset variable to fluid sim settings, which can be used to display baked fluid sims at different times. Eventually this could be replaced by real NLA strips for cached data, but until then this is a simple way to have more flexible cache result usage.
Not strictly a BCon3 patch, but after IRC discussion with Genscher, ZanQdo and kaito decided to commit it anyway, since it's a small feature and makes fluid sim a bit more usable. Similar patch for point cache (particles, smoke, cloth) is being worked on as well.
This commit restores support for freezing or speeding up physics sims. Animate
the "Speed" parameter under Domain->Time, which controls a multiplier factor for
the rate at which the sim proceeds (i.e. the old "Fac-Tim" setting).
Notes:
* Subversion bumped to 4 to patch up defaults for new value so that old sim
files will still run correctly
* Names/descriptions could do with some tweaking
* Porting this across was not that obvious since quite a bit of stuff had
changed (as in, been cleaned up). However, from tests so far, it seems to work
well.
