refactored obstacle velocities

applied some fixes that automatic analyze tool suggested

added particle velocity scaling

automated some UI selections

now smoke domains set volume cache automatically, liquid domains set surface cache automatically

setting solver res here is obsolete

no need to set this explicitly. solver only threw expection when loading blend files created with vanilla blender. versioning support will handle this in the future.

added support for particle velocities

now saving and loading particle velocities from uni files

implemented new caching approach

caching is now divided into two parts: surface and volume caching. the reasooning behind this is that for some setups (e.g. liquid + particles) there needs to be a way to cache both the mesh (surface caching) and particles (volumetric caching). Also, smoke scenes might use meshes in the future (e.g. vortex sheets)

refactored new option for particles and mesh

implemented viewport display switcher for liquids

previously the viewport switcher only worked for smoke. only drawback is now that toggling the viewport switcher resets the cache(probably because of recalculating liquid mesh). baked caches however stay. issue remains a todo.

added cfl field to UI

adjustable cfl number lets users better control timesteps

added particle instance variable initialization and cleaned up a bit

added new cache option that supports mesh and FLIP particle export

fix for particle system sanity check

sanity was a little to late. needs to be before any file reading (getter) operation

automatically set domain mesh draw type for particles and mesh mode

for particles it is more convenient to have a wire frame, for meshes the solid mode is better

added narrow band field to UI

being able to control the particle band width is useful when working with the FLIP particle cache. with a higher band width you can fill up the entire fluid volume with particles

fix for required shift when domains moves

when domain moves away from position it was originally simulated it, a shift needs to be added to the particle coords. the was opposite to what is needed.

set manta particle radius in particle system as well

fix for preconditioner and closed domains

closed domains require zero pressure fixing enabled for the preconditioner to work

fixed domain border collision key mapping

textual descriptions of borders did not match blender views

filter out dead particles

mantaflow stores dead particles for internal purposes. in blender we just skip them, they dont need to be shown in the UI
