Depsgraph: Corrections to IK solver without tip included

Tip itself should be handled separately after the IK solver is done.

This fixes rig setup of typewriter from ED.

Well, not fully, there's another fix for modifiers name to be applied
in master branch.

Merge remote-tracking branch 'origin/master' into cycles-ptex-49

Consistently use "ptex_rects" instead of "ptex_regions"

Partial instancing feature for the ParticleInstance modifier.

This allows using the same particle system for multiple objects without
creating too much repetitiveness. Each instance object can select a
range of the particles to actually use for instancing (default 1.0 means
all particles are used). To further avoid overlap with multiple
instancing objects, the offset value can be used to make each system
use a specific range of particles.

First pass at fixing Ptex texpaint resolution undo/redo

Seems to work OK, but need to clean up the API to make it work
better. Want to make sure there are no unexpected issues first though.

Merge branch 'master' into asset-experiments

Use new point cache API in the cloth modifier.

Currently broken.

Final nitpicks:

No warning for out of camera, rename darken to factor/strength (since
color can be actually be light)

replace 'SSAO' option with 'Ambient Occlusion'

more descriptive, and SSAO is more for developers/shader writers

error in last commit

use common GPU_fx_compositor_ prefix

also rename darkening -> darken

Tidy up the UI a bit for DOF

Add initialization functions for GPU compositing

move comment to view3d

correction to last comment

Comment out DOF initialization, its not used

This is a special case

Also write DOF if it exists.
