Driver error warnings are now only printed to the console when Blender is run
using the -d flag

This prevents a stream of error messages flooding the console when working with
particular rigs which may have a few broken controls. In general, riggers now
have a better alternative by using the filtering tools in the Graph Editor.

Bugfix [#34688] Auto-Keying doesn't include custom properties when pasting poses

Previously, Paste Poses only used the LocRotScale Keying Set for autokeyframing
purposes. This was fine for most purposes, but with many rigs these days also
using custom properties for important posing functions, it's important that we
include those here too.

code cleanup: misc warnings/style

fix for incorrect use of 'bool', also fix 2 older bugs in fly mode.
- panning didnt keyframe translation animation.
- when checking to key translation: speed `float` was converted to an `int` then treated as a bool, now check (speed != 0).

Fix #34700: cycles depth of field now works with orthographic cameras too.

code cleanup: use bool where values are true/false, for view3d and related functions.

I18n users request: add the ability to use a translated name for newly added/created objects or other datablocks.

This simply adds a third "translation type" (in addition to iface and tip), "new data", with relevant user settings flag and helper funcs/macros (and py api).

Currently implemented name translation when adding new objects, as well as modifiers and constraints, will add the others (cd layers, scenes, perhaps nodes [though I think they do not need this], etc.) later.

Changes to compositor output node

Make it so compositor output node wouldn't be calculated
when Render Result image is not visible on the screen.
This makes compositor tree editing more friendly and
faster.

Also, if there's no viewer image visible on the screen
viewer nodes wouldn't be handled.

Final rendering keeps unchanged for now.

This solves issues when for performance artists are
disconnecting compo output node before tweaking values
in compositor and forgets to attach compo output
node before sending file to the farm.

When using border rendering, use the same border for compositor

This makes compositing as fast as it's possible in this case.

The only thing is border render+crop will still give funcy
results. This is the next thing to be solved in compositor.

Bugfix [#34710] Crash on duplicating object with cloth modifier.

Caused by last commit by me.

Prefetching for movie clips

This commit basically implements frames prefetching for
movie clip datablock.

Number of frames to be prefetched is controlled in User
Preferences, System tab, Prefetch Frames option.

Currently prefetching is destructive-less for movie cache,
meaning mo frames will be removed from the cache when while
prefetching. This is because it's half of simplier to
implement, but it also makes sense from tracking point of
view -- we could want to playback in both directions and
removing frames from behind time cursor is not always a
good idea.

Anyway, smarter prefetching strategy could be developed
later.

Some implementation notes:

- Added MEM_CacheLimiter_get_memory_in_use function to get
memory usage of specified memory limiter.

- Fixed prototype of MEM_CacheLimiter_get_maximum which
was simply wrong (used wrong data type for output).

- Added some utility functions to movie clip and movie
cache for direct cache interaction and obtaining cache
statistics.

- Prefetching is implemented using general jobs system.
which is invoking from clip draw function.

- Prefetcing will stop as soon other job or playback starts.
This is done from performance point of view. Jobs will
likely require lots of CPU power and better to provide
whole CPU to it.

Playback is a bit more complicated case. For jpeg sequence
playback prefetching while paying back is nice. But trying
to prefetch heavy exr images and doing color space
conversion slows down both playback and prefetching.

TODO:

- Think of better policy of dealing with already cached frames
(like when cached frames from other clips prevents frames
from current clip to be prefetched)

- Currently a bit funky redraw notification happens from
prefetch job. Perhaps own ND_ is better to have here.

- Hiding clip while prefetch is active in theory shall stop
prefetching job.

- Having multiple clips opened on file load will prefetch
frames for only one of them.

OSX/tablet: fix a longstanding bug with certain devices and a cornercases

Small fix: make node backdrop draw with nearest-pixel filter, so it zooms in
showing pixels. Issue was it also blurred image at zoom level 1... maybe subpixel
issue. Anyway - for inspecting exact composite results, zooming in showing pixels
is nicer anyway.

- add knife project to toolbar.
- when running knife project, disable vertex selection since it may select areas between the newly cut regions.
add EDBM_selectmode_disable() function since loopcut does this too.
- (optimization) avoid looping over all geometry when flushing and no selection exists.

Fix #34694. This was actually a bug in the compositor's Bokeh Blur operation. It was writing outside of allocated memory in case of (0, 0) size buffers, with the usual unpredictable results.

add option to convert grease pencil into poly line directly.

Without this, bezier curves at 12 resolution are very high detail for many tasks when converted from freehand strokes.
so add the option to convert 1:1 grease pencil points to curve polygons.

also add use_handles option to curve conversion which is used when converting beziers to poly lines.

When making a node group always add one input and one output node, regardless of whether there are any exposed sockets. The standard common case is that some sockets will eventually have to be exposed anyway, and it's easier to just delete the unused node instead of having to look it up in the menu.

add back -Wredundant-decls, just not for older gcc's

Fix for #34708 and #34709, cycles group nodes were not working well with 0 or 2+ group input/output nodes.

The issue here was that the proxy nodes created for connecting extern group node sockets to the internal nodes were generated by the input/output nodes themselves.

0 input/output nodes: there would be no proxy that external group node sockets can map to
2+ input/output nodes: additional nodes would overwrite entries from previous nodes, so that only one of the input/output nodes would be used.

Solution is to always generate exactly 1 proxy node for every group socket in advance, regardless of whether it is used internally. Internal node sockets can then all map to this proxy node.

In the case out output nodes there should only ever be one active node, otherwise the connection to the proxy would be ambiguous. For this purpose the NODE_DO_OUTPUT flag has been exposed to RNA, so that cycles can check it and only use the active output.
