* optimized threading
* break out with glare node
* Added OpenCL kernels compatible with AMD still need some testing.

Cycles: first step for implementation of non-progressive sampler that handles
direct and indirect lighting differently. Rather than picking one light for each
point on the path, it now loops over all lights for direct lighting. For indirect
lighting it still picks a random light each time.

It gives control over the number of AA samples, and the number of Diffuse, Glossy,
Transmission, AO, Mesh Light, Background and Lamp samples for each AA sample.

This helps tuning render performance/noise and tends to give less noise for renders
dominated by direct lighting.

This sampling mode only works on the CPU, and still needs proper tile rendering
to show progress (will follow tommorrow or so), because each AA sample can be quite
slow now and so the delay between each update wil be too long.

update themes for new colors, patch by Brendon Murphy

Fix cycles crash when viewport camera border goes out of view.

Fix cycles object_flag array being allocated too big.

always use bicubic sampler for the scale node with the new compositor since it worked like this in the old compositor.

this ignores the sampler passed and could be done in a nicer way so left this as an ifdef so it can be easily redone.

- highlight active mask layers.
- remove keyframes when all layer data is removed.

tint non-active mask layers grey

Fix #31780, cycles nested group rendering broken. Was using the dupli object 'index' member to identify dupli objects, but this is not unique and in fact just 0 in most cases. Needs to use a simple dupli list counter instead.

code cleanup: use const float's where possible and specify vector size.

Collada: fixed a few loops to only loop over the list of exported objects, instead of the current scene.

Merging r47793 through r47805 from trunk into soc-2011-tomato

Default value for frame offset should be 0

patch #31794 Collada: make exporter more robust, now uses BKE_object_relational_superset()

Added frame offset slider to clip datablocks

In contrast to start_frame (which affects on where footage actually
starts to play and also affects on all data associated with a clip
such as motion tracking, reconstruction and so on) this slider only
affects on a way how frame number is mapping to a filename, without
touching any kind of tracking data.

The formula is:
file_name = clip_file_name + frame_offset - (start_frame - 1)

patch #31794 Added new function BKE_object_relational_superset()

Fix camera curve in clip editor not being remapped by a clip's start frame
