This option (alongside the Ease In/Out/InOut options already available) aims to make it
easier to get an initial curve that looks closer to the one you were expecting, by
automatically picking whether Ease In or Ease Out should be used based on the type of
interpolation being used for the curve segment in question.
Notes:
* The types chosen may need some adjustments (e.g. using ease in-out instead of just ease in)
* This does break compatability with files saved in previous dev builds, but only
if you were using Bounce/Elastic/Back with "Ease In"
When the dopesheet was open, "keyframe edited" events from the graph editor
(i.e. fired whenever any properties on keyframes or FModifiers are changed)
would trigger the dopesheet to synchronise selection states of anim channels
and ensure that FCurve autocolours are initialised correctly.
This however was undesired when editing properties in the graph editor. Now,
made it so that keyframe adding/removing operators use different notifier flags
to specify that the channels might have changed + need colour syncing, and
adjusted the dopesheet updating logic to fit
View2D had some inconsistencies making it error prone in some cases.
- Inconstant checking for NULL x/y args.
Disallow NULL args for x/y destination pointers, instead add:
- UI_view2d_region_to_view_x/y
- UI_view2d_view_to_region_x/y
- '_no_clip' suffix wasn't always used for non-clipping conversion,
switch it around and use a '_clip' suffix for all funcs that clip.
- UI_view2d_text_cache_add now clips before adding cache.
- '_clip' funcs return a bool to quickly check if its in the view.
- add conversion for rectangles, since this is a common task:
- UI_view2d_view_to_region_rcti
- UI_view2d_region_to_view_rctf
For a long time, one of the bottlenecks when drawing summary channels in the dopesheet
(especially with many objects) was how the long keyframes feature (i.e showing holds
between keyframes) got built. Specifically, it was the step where we check on the previous
keyframe to see whether there's a hold between those two.
The old code performed some elaborate checks, which made sense back when we used to handle
certain summary channels (e.g. object-action/ipo, and groups IIRC) differently. However,
nowadays, everything just does it by going over the FCurves one by one, so the offending
code wasn't really providing much benefit. Unless I've forgotten some other reason why
that old method is necessary, this commit should provide a decent speedup here, making
things somewhat interactive now (if still a bit jerky).
Other Tweaks:
1) Introduced float-precision threshold when checking to see whether an existing long
keyframe could be reused. This should hopefully reduce the number of fp-jitter issues
when creating summaries for many channels, reducing the number of duplicates created.
2) Precompute colours used for shading the long keyframes, instead of recomputing for
each block.
This commit introduces support for a number of new interpolation types
which are useful for motion-graphics work. These define a number of
"easing equations" (basically, equations which define some preset
ways that one keyframe transitions to another) which reduce the amount
of manual work (inserting and tweaking keyframes) to achieve certain
common effects. For example, snappy movements, and fake-physics such
as bouncing/springing effects.
The additional interpolation types introduced in this commit can be found
in many packages and toolkits (notably Qt and all modern web browsers).

Basic idea is to check whether an element is visible or not, and ignore those that are hidden, during move up/down.

In many BI shader setups, the material which owns the nodetree is often itself
included as a node in that nodetree (i.e. to provide the base colour for that
mesh). This would often result in the material (and its subtree) getting included
in the dopesheet results twice.
FCurve Noise Modifer now has an extra float property which offsets the noise in time.
This is useful for creating follow through in procedurally animated noise.
For example, if you've used a noise modifier on a parent bone to add additional movement,
a quick and easy way to add overlapping motion is to create copies of that modifier on
its children, and then offset the time those curves play at. See this in action at:

- deduplicate timecode_simple_string from image.c
- replace V2D_UNIT_SECONDSSEQ with V2D_UNIT_SECONDS
- avoid possible buffer overflow bugs (sprintf -> BLI_snprintf)
- remove option not to use timecode and split into 2 functions

libraries view not working.
This was disabled in the operator, there may have been a reason for this at
some point, but I can't see any reason to disallow it in the current code or
find a good reason why it was done in the commit logs.
* Version patching fixes for theme settings
* Added missing support for NLA (needed for the keyframes drawn in the action lines)
* Fix for a lack of contrast between selected and unselected extreme keyframe type
(restoring it back to the pre-patch color scheme)
* Fix for keyframes on protected channels not being drawn with partial opacity
This patch makes it possible to customise the colours used for the different
keyframe types (Keyframe, Breakdown, Extreme, Jitter) and the border colours
(normal and selected).

Summary:
This completly changes the way modal numinput is handled. Now, edited expression is a string, which then gets unit- and py-evaluated to get a float value.
We gain many power and flexibility, but lose a few "shortcuts" like '-' to negate, or '/' to inverse (if they are really needed, we still can add them with modifiers, like e.g. ctrl-/ or so).
Features:
- units (cm, ", deg, etc.).
- basic operations from python/BKE_unit (+, *, **, etc.), and math constants and functions (pi, sin, etc.).
- you can navigate in edited value (left/right key, ctrl to move by block) and insert/delete chars, e.g. to fix a typo without having to rewrite everything.
- you can go to next/previous value with (ctrl-)TAB key.
- As before, hitting backspace after having deleted all leading chars will first reset the edited value to init state, and on second press, the whole "modal numinput" editing will be cancelled, going back to usual transform with mouse.
Notes:
- Did not touch to how values are shown in header when modal numinput is not enabled (would do that in another commit), so this is still quite inconsistent.
- Added back radian support in BKE_unit.
- Added arcminute/arcsecond to BKE_unit.
(those unit changes affect all angle UI controls, btw, so you can now enter radians or longitude/latitude values when in degrees units).

There was probably a reason in the past why this wasn't desirable, but since we allow
bones to be properly selected when clicking on corresponding channels here, we may as
well allow this case too.
