Curves: read/write orders, knots, weights and radiuses.

Curves: Trim tool

Fixed an issue with ratio_to_segment.

Generate a buffer texture for passing the control strand locations to the shader.

This should enable the strand geometry shader to interpolate control strands
with appropriate vertex attributes for indices and weights.

removed mesh scaling. better do this in smoke.c and keep cpp wrapper independent from mesh size

fixed return type for vertex getter

Import: report a message in the UI in case opening a file fails.

Cleanup.

Fix crash dereferencing NULL ptr.

Merge branch 'master' into soc-2016-layer_manager

Use separate buffers for control strand and root vertices.

This is important so we can put control strands into a buffer texture,
and pass it to the geometry shader for generating strands.

Start off with some very simple own code for vert/frag/geom strand shader.

Update Alembic library to version 1.6, remove support for HDF5.

ALthough the FindHDF5 cmake module is still present for people to use,
HDF5 is removed from install_deps.sh. From now on, Alembic built with
HDF5 support is considered legacy and not "officially" supported.

Draw render strands as simple point primitives.

The geometry shader will eventually turn these points into full strand curves.

Generate a number of "roots" for render hairs on the mesh surface.

These root points will be used as input for the strand shader to generate
the interpolated render strands.

Use the show_control_strands toggle for switching control hair display on/off.

Also use the basic edge shader for control hairs, the generated GLSL shader is
only needed for drawing render strands.

Merge branch 'soc-2016-pbvh-painting' of git.blender.org:blender into soc-2016-pbvh-painting

NURBS: pad start and end of knots arrays with dummy knots to accomodate
for other software.

Avoid recursive drawing of layer group members

Fix layer selection broken with collapsed groups

Correct direction of layer group collapse icon
