Fix T46757: Blender Close when try to render an Animation

Was a missing NULL-pointer check in recent frameserver commit.

Cleanup: rename line to segments, avoids confusion

Differentiate between lines and segments.

Fix T46749: Texture paint & shadeless mode fails

Using shadeless did nothing in texture-paint mode.
(regression in 2.76)

Frame Server: use main render loop

Avoid duplicate checks/updates when the frameserver is used.

Fix T46641: Bicubic transform on ID channel is not bicubic

Better support of bicubic sampling of ID mask output.

The idea is to generate ID mask into a temporary buffer which is then being
interpolated using current sampling method.

This works fine for upscaling or rotating the ID mask but does not work for
scaling down. This is much-much bigger problem of the compositor design and
can't really be solved currently. Same will happen with other nodes like
blur for example.

Fix T46320: New Depsgraph: Auto-IK doesn't work

The issue is caused by transform tool temporary affecting on the pose
constraints, which actually changes the way how pose is to be evaluated.

This isn't ideal patch from the performance point of view, but only
limited to the new depsgraph, so we've got some time to work on partial
graph updates.

Fix T46729: Render result different between animated and still renders

The issue was in fact a feedback loop between render database init which needs
to know which render layers to initialize and scene update for newframe which
needs to know which layers to update.

Worked around by updating scene animation before render database initialization
which isn't really ideal, but doesn't really have much better alternative.

Fix T46748: OpenEXR output different when frame saved with F3 vs. in an animation

The issue was caused by the image save operator ignoring Z-Buf if the input
buffer due to the way how IMB_dupImBuf() worked. There's no reason to to
ignore z-buf on imbuf duplication, it only asks for issues in the future.

Fix error cutting node links

Accessing theme from outside drawing code isn't reliable, pass space-type.

Transform input: don't change initial cursor value

Store previous coords in cursor data instead.

Fix for factory settings loading without UI

When load-ui was disabled, resetting factory settings kept existing UI too.

Cleanup: unused defines

Correct error in own matrix normalize commit

Cleanup: replace more direct id->us handling by calls to BKE_library API.

Cleanup: readfile.c: use id_us_ensure_real() instead of own custom 'at least one user' handling.

Note that in master this is mere cleanup, which shall not change much things
(aside from FAKE_USER now being taken into account here too), and mostly
makes things more consistent, but in id-remap branch this becomes mandatory
due to better handling of this ugly 'ensure_real' stuff re user count.

Correct assert in own last commit

Fix T46741: Transform ignores constraint space

Calling transform operator from Python didn't apply the constraints space.

And another fix to psys ID handling - ParticleSystem->part **is** user counted!

Fix (unreported) foreach ID looper going over some psys' IDs twice...

OpenGL Render: Support full-sample Anti-Aliasing

This brings back old (slower), higher quality method.
Useful since graphics cards often use a faster MSAA which only oversamples edges.
