MTFACE customdata is not suitable or necessary for caching, so disable
it.

Copy rgba components of MCol explicitly to the Alembic C4f type to avoid
potentially different ordering.

Make sure the cache baking job cancels properly when interrupted in the
first stage.

Replacing boundbox temporarily during drawing is dangerous, since it
can be freed at any point.

Luckily we only need the boundbox locally for testing dupli visibility.

Distinguish realtime/render setting in the Object writer.

Now the derived_render mesh version is created locally when writing
render results.

CD_NORMAL support for mesh customdata caching.

Make sure mesh data is really stored and reconstructed from the cache
entirely.

Also the code is much better structured now, moving toward a more
standardized sample/schema class definition.

Safeguard against crashes from invalid Alembic file paths by returning
NULL archive pointers.

This allows writer/reader code to test against obvious archive errors
easily and is unmistakable.

Added customdata writers/readers for missing mesh edge, poly and loop
data.

Removed group pointer from cache libraries and use object->cachelib
pointer instead.

This change makes it possible to have group duplicators using different
versions of a cache.

Disable the bake operator if cache reading is enabled.

Re-baking cache results is not technically prohibited, but not useful
and allowing only read or write selectively gives a nicer workflow.

Test for NULL archive pointer when writing as well.

This should not usually happen because the operator asks for permission
to delete the file prior to writing, but should be checked nevertheless.

Skip drawing of particle systems (including hair) when using cache
duplis.

Particle systems can not be overridden from caches easily, there are too
many strings attached to the data and code to make this reliable.
Instead, a new simplified data structure for reading hair from caches
will be added, which replaces drawing and rendering of particle data.
The original particle data is not updated through duplis, so is usually
out of sync and should not be displayed.

Calculate bounding boxes for cached DMs to avoid visual popping when
using the original Object's bb.

Cycles support for dupli caches.

If a cache is read-enabled cycles will now use the cached mesh data
instead of dupli results.

Removed unused variable.

Main argument is no longer needed for cache reading, the cachelib is
now given explicitly.

Fix for wrong ID code used in RNA->idcode mapping.

UI cleanup and a bit nicer workflow by treating read/write mode like
an enum toggle.

Mesh overrides for duplis from cached Alembic data.

If a duplicator has cached data it will now replace the derivedFinal
mesh of objects with the cached version for drawing.

This is a compromise atm: It would be better to actually draw derived
meshes directly, so that we don't have to modify objects. Then we could
also have multiple different instances of the same orignal object
(in whatever way these might be defined). DNA Objects would then be
totally separate from duplis, but at this point the drawing and render
code makes this unfeasible.
