Fix and use block caching from UI draw code.

Seems to work nice now.

Alebic: Fix compilation error of blenderplayer target on buildbot

Use the same weight buffer for boundary as vertex weights

Don't write deltas to disk (keep as runtime cache)

rename boundverts -> positions_num

Add vertex-group invert option

don't store vertex weights in the modifier

I'd rather use a different way of enforcing 'deltas' to be recalculated.

Perhaps using a notifier.

Writer for strand data and extension for the new motion state data.

Unlike the particle hair writer this one does not work with the particle
system data but the new Strands data. This will allow successive
manipulations of cached hair data by first storing the initial particle
grooming data ("hair edit"), read this data from the cache into a
Strands instance, then apply hair simulation and write the result back
into a second Strands cache.

Added optional motion state data to Strands.

This implements the distinction between the strand goal position
(grooming data, shape keys) and the result of dynamics simulation.

minor rename RNA/flags

Baking API for cache modifiers.

Cache baking means the cache modifier should read input caches over the
given frame range and produce the correct output for writing into the
output cache file.

Cache modifiers can optionally implement a 'bake' function. This is used
through a bake operator from the cache modifier panel. Baking is
executed in a job, which will help with cancelling bakes and displaying
status info.

Add loop-angle-weighted smoothing

Add in defines for different smoothing methods

(so we can test them)

BGE: BL_Shader.setUniformEyef(): new uniform type to pass stereo eye value.

BL_Shader.setUniformEyef() python method to define a uniform that will
receive the eye value as a float: 0.0 when rendering the left eye, 0.5
when rendering the right eye.
This can be used in a shader to split a 3D texture sent to the GPU by
VideoDeckLink as the left+right eye frame is sent as a single texture in
bottom/top order.

Work around a bug in VideoDeckLink with the the DVP library: the call to
dvpBindToGLCtx() fails for the first frame. This needs to be investigated
but for now catch the exception thrown by this condition and release the
decklink frame anyway as otherwise it corrupts the reference count of the
decklink device.

pre-divide vertex-count, avoid zero checks in smooth loop
