Support for writing derived mesh data from point cache modifier between
other modifiers.

Previously this was simply using the derivedFinal of the object. Now
the point cache has its own writer instance which is writing samples
during the regular modifier evaluation, rather than directly being
called by the bake operator.

Merge branch 'master' into alembic_pointcache

Integration of point caching into the modifier stack.

This ensures that the modifier stack is disabled up to the last valid
cache modifier. This cache modifier then provides a derived mesh as
input for the remaining modifier stack tail, or as final output if no
other modifiers follow.

Fix scons linking of Alembic and HDF5 and additiona Ilmbase/OpenEXR libraries.

Some changes to the Alembic build script for specifying the install
prefix and build type.

Alembic build files are still horrible, have to find a reliable solution
for that.

Reverted changes to the Mesh Cache modifier, this functionality is now
being implemented in the new Point Cache modifier instead.

Introduced a new modifier "Point Cache" for recording cache data at
user-defined points in the modifier stack.

These will replace the preliminary test changes in the mesh cache
modifier.

Moved C API functions for individual data types into their respective
files to simplify the code structure.

Partial scons build files for pointcache library and Alembic
dependencies.

This is not yet functional, the Alembic linking is quite tricky.

Support for topology changes by making the mesh cache modifier into a
constructive modifier.

Warning! this may well break with the deform-only file types (MDD and
PC2), so it needs careful review before considering trunk merge. In any
case, this is just a test for Alembic import.

Alembic reading in the Mesh Cache modifier.

Note that this only works with deformation atm.

Implemented basic OPolyMesh Alembic writing.

Only includes vertex positions and poly loops for now. The standard
mesh schema in Alembic includes also UV layers and some other standard
data, but all the necessary Blender custom data layers can be stored in
these files as well.

Writer/Reader classes for the mesh cache modifier.

Dummy point cache instance in the mesh cache modifier, as a test bed for
mesh data export/import.

Fix for changed function signature in freestyle code.

Extra check for cache user info when running the generic point cache
export operator.

A couple of fixes for changed Blender functions and the new
EvaluationContext needed for evaluating the scene during baking.

Linux library linking is now in a cmake macro file.

Include Alembic build arguments in BUILD_INFO.txt.

Install Alembic in $INST path directly, use the subfolder created by
Alembic build files themselves.
